Porn bots are more or less ingrained in the social media experience, despite platforms’ best efforts to stamp them out. We’ve grown accustomed to seeing them flooding the comments sections of memes and celebrities’ posts, and, if you have a public account, you’ve probably noticed them watching and liking your stories. But their behavior keeps changing ever so slightly to stay ahead of automated filters, and now things are starting to get weird.

While porn bots at one time mostly tried to lure people in with suggestive or even overtly raunchy hook lines (like the ever-popular, “DON'T LOOK at my STORY, if you don't want to MASTURBATE!”), the approach these days is a little more abstract. It’s become common to see bot accounts posting a single, inoffensive, completely-irrelevant-to-the-subject word, sometimes accompanied by an emoji or two. On one post I stumbled across recently, five separate spam accounts all using the same profile picture — a closeup of a person in a red thong spreading their asscheeks — commented, “Pristine 🌿,” “Music 🎶,” “Sapphire 💙,” “Serenity 😌” and “Faith 🙏.”

Another bot — its profile picture a headless frontal shot of someone’s lingerie-clad body — commented on the same meme post, “Michigan 🌟.” Once you’ve noticed them, it’s hard not to start keeping a mental log of the most ridiculous instances. “🦄agriculture” one bot wrote. On another post: “terror 🌟” and “😍🙈insect.” The bizarre one-word comments are everywhere; the porn bots, it seems, have completely lost it.

Really, what we’re seeing is the emergence of another avoidance maneuver scammers use to help their bots slip by Meta’s detection technology. That, and they might be getting a little lazy.

“They just want to get into the conversation, so having to craft a coherent sentence probably doesn't make sense for them,” Satnam Narang, a research engineer for the cybersecurity company Tenable, told Engadget. Once scammers get their bots into the mix, they can have other bots pile likes onto those comments to further elevate them, explains Narang, who has been investigating social media scams since the MySpace days.

Using random words helps scammers fly under the radar of moderators who may be looking for particular keywords. In the past, they’ve tried methods like putting spaces or special characters between every letter of words that might be flagged by the system. “You can't necessarily ban an account or take an account down if they just comment the word ‘insect’ or ‘terror,’ because it's very benign,” Narang said. “But if they're like, ‘Check my story,’ or something… that might flag their systems. It’s an evasion technique and clearly it's working if you're seeing them on these big name accounts. It's just a part of that dance.”

That dance is one social media platforms and bots have been doing for years, seemingly to no end. Meta has said it stops millions of fake accounts from being created on a daily basis across its suite of apps, and catches “millions more, often within minutes after creation.” Yet spam accounts are still prevalent enough to show up in droves on high traffic posts and slip into the story views of even users with small followings.

The company’s most recent transparency report, which includes stats on fake accounts it’s removed, shows Facebook nixed over a billion fake accounts last year alone, but currently offers no data for Instagram. “Spammers use every platform available to them to deceive and manipulate people across the internet and constantly adapt their tactics to evade enforcement,” a Meta spokesperson said. “That is why we invest heavily in our enforcement and review teams, and have specialized detection tools to identify spam.”

Last December, Instagram rolled out a slew of tools aimed at giving users more visibility into how it’s handling spam bots and giving content creators more control over their interactions with these profiles. Account holders can now, for example, bulk-delete follow requests from profiles flagged as potential spam. Instagram users may also have noticed the more frequent appearance of the “hidden comments” section at the bottom of some posts, where comments flagged as offensive or spam can be relegated to minimize encounters with them.

“It's a game of whack-a-mole,” said Narang, and scammers are winning. “You think you've got it, but then it just pops up somewhere else.” Scammers, he says, are very adept at figuring out why they got banned and finding new ways to skirt detection accordingly.

One might assume social media users today would be too savvy to fall for obviously bot-written comments like “Michigan 🌟,” but according to Narang, scammers’ success doesn’t necessarily rely on tricking hapless victims into handing over their money. They’re often participating in affiliate programs, and all they need is to get people to visit a website — usually branded as an “adult dating service” or the like — and sign up for free. The bots’ “link in bio” typically directs to an intermediary site hosting a handful of URLs that may promise XXX chats or photos and lead to the service in question.

Scammers can get a small amount of money, say a dollar or so, for every real user who makes an account. In the off chance that someone signs up with a credit card, the kickback would be much higher. “Even if one percent of [the target demographic] signs up, you're making some money,” Narang said. “And if you're running multiple, different accounts and you have different profiles pushing these links out, you're probably making a decent chunk of change.” Instagram scammers are likely to have spam bots on TikTok, X and other sites too, Narang said. “It all adds up.”

The harms from spam bots go beyond whatever headaches they may ultimately cause the few who have been duped into signing up for a sketchy service. Porn bots primarily use real people’s photos that they’ve stolen from public profiles, which can be embarrassing once the spam account starts friend requesting everyone the depicted person knows (speaking from personal experience here). The process of getting Meta to remove these cloned accounts can be a draining effort.

Their presence also adds to the challenges that real content creators in the sex and sex-related industries face on social media, which many rely on as an avenue to connect with wider audiences but must constantly fight with to keep from being deplatformed. Imposter Instagram accounts can rack up thousands of followers, funneling potential visitors away from the real accounts and casting doubt on their legitimacy. And real accounts sometimes get flagged as spam in Meta’s hunt for bots, putting those with racy content even more at risk of account suspension and bans.

Unfortunately, the bot problem isn’t one that has any easy solution. “They're just continuously finding new ways around [moderation], coming up with new schemes,” Narang said. Scammers will always follow the money and, to that end, the crowd. While porn bots on Instagram have evolved to the point of posting nonsense to avoid moderators, more sophisticated bots chasing a younger demographic on TikTok are posting somewhat believable commentary on Taylor Swift videos, Narang says.

The next big thing in social media will inevitably emerge sooner or later, and they’ll go there too. “As long as there's money to be made,” Narang said, “there's going to be incentives for these scammers.”

As the Senate considers the bill that would force a sale or ban of TikTok, lawmakers have heard directly from intelligence officials about the alleged national security threat posed by the app. Now, two prominent senators are asking the office of the Director of National Intelligence to declassify and make public what they have shared.

“We are deeply troubled by the information and concerns raised by the intelligence community in recent classified briefings to Congress,” Democratic Senators Richard Blumenthal and Republican Senator Marsha Blackburn write. “It is critically important that the American people, especially TikTok users, understand the national security issues at stake.”

The exact nature of the intelligence community's concerns about the app has long been a source of debate. Lawmakers in the House received a similar briefing just ahead of their vote on the bill. But while the briefing seemed to bolster support for the measure, some members said they left unconvinced, with one lawmaker saying that “not a single thing that we heard … was unique to TikTok.”

According to Axios, some senators described their briefing as “shocking,” though the group isn’t exactly known for their particularly nuanced understanding of the tech industry. (Blumenthal, for example, once pressed Facebook executives on whether they would “commit to ending finsta.”) In its report, Axios says that one lawmaker “said they were told TikTok is able to spy on the microphone on users' devices, track keystrokes and determine what the users are doing on other apps.” That may sound alarming, but it’s also a description of the kinds of app permissions social media services have been requesting for more than a decade.

TikTok has long denied that its relationship with parent company ByteDance would enable Chinese government officials to interfere with its service or spy on Americans. And so far, there is no public evidence that TikTok has ever been used in this way. If US intelligence officials do have evidence that is more than hypothetical, it would be a major bombshell in the long-running debate surrounding the app.

A team of university security researchers has found a chip-level exploit in Apple Silicon Macs. The group says the flaw can bypass the computer’s encryption and access its security keys, exposing the Mac’s private data to hackers. The silver lining is the exploit would require you to circumvent Apple’s Gatekeeper protections, install a malicious app and then let the software run for as long as 10 hours (along with a host of other complex conditions), which reduces the odds you’ll have to worry about the threat in the real world.

The exploit originates in a part of Apple’s M-series chips called Data Memory-Dependent Prefetchers (DMPs). DMPs make the processors more efficient by preemptively caching data. The DMPs treat data patterns as directions, using them to guess what information they need to access next. This reduces turnarounds and helps lead to reactions like “seriously fast,” often used to describe Apple Silicon.

The researchers discovered that attackers can use the DMP to bypass encryption. “Through new reverse engineering, we find that the DMP activates on behalf of potentially any program, and attempts to dereference any data brought into cache that resembles a pointer,” the researchers wrote. (“Pointers” are addresses or directions signaling where to find specific data.) “This behavior places a significant amount of program data at risk.”

“This paper shows that the security threat from DMPs is significantly worse than previously thought and demonstrates the first end-to-end attacks on security-critical software using the Apple m-series DMP,” the group wrote.

The researchers named the attack GoFetch, and they created an app that can access a Mac’s secure data without even requiring root access. Ars Technica Security Editor Dan Goodin explains, “M-series chips are divided into what are known as clusters. The M1, for example, has two clusters: one containing four efficiency cores and the other four performance cores. As long as the GoFetch app and the targeted cryptography app are running on the same performance cluster—even when on separate cores within that cluster — GoFetch can mine enough secrets to leak a secret key.”

The details are highly technical, but Ars Technica’s write-up is worth a read if you want to venture much further into the weeds.

But there are two key takeaways for the layperson: Apple can’t do much to fix existing chips with software updates (at least without significantly slowing down Apple Silicon’s trademark performance), and as long as you have Apple’s Gatekeeper turned on (the default), you won’t likely install malicious apps in the first place. Gatekeeper only allows apps from the Mac App Store and non-App Store installations from Apple registered developers. (You may want to be extra cautious when manually approving apps from unregistered developers in macOS security settings.) If you don’t install malicious apps outside those confines, the odds appear quite low this will ever affect your M-series Mac. 

Final Fantasy 7 Rebirth dropped only a few weeks ago, but fans of the series won't have to wait long at all to play a new addition to another recent entry. The Rising Tide, the second paid expansion for Final Fantasy XVI, will arrive on April 18.

The release date was revealed at a PAX East panel, where it was announced that The Rising Tide will cost $20. However, if you haven't already picked up the previous paid DLC, Echoes of the Fallen, you can snap up both for $25 through a discounted expansion pass.

The Rising Tide will see Clive and his cohorts travel to the hidden land of Mysidia. They'll "uncover the tragic history of a forgotten people" as they look for the dominant of Leviathan, a long-lost Eikon of water. As with Echoes of the Fallen, the action takes place before the ending of the main game.

As the title and description suggest, you'll get to wield an array of water-based attacks, including a "sea-spitting serpent." The PlayStation Blog also teases that Clive will find another power on his journey. Meanwhile, the trailer shows off the battle with Leviathan, which takes place on the surface of a lake.

Those who beat The Rising Tide and the main game will gain access to a new endgame mode called Kairos Gate. You'll battle through 20 levels of increasing difficulty, taking down one wave of enemies after another. You can earn new materials and weapons for Clive through this mode. 

On top of all that, Square Enix will release a free update for Final Fantasy XVI on April 18 that includes a string of quality-of-life upgrades. For one thing, you'll be able to instantly return to the NPC who gave you a quest with the Quick Complete option. A Skill Set feature will let you save up to five Feat and Ability loadouts. In a positive update for accessibility, you'll be able to remap the controls as you see fit.

Iconic singer Joni Mitchell has put her music back on Spotify more than two years after she left the platform as a protest against it hosting misinformation about COVID-19 vaccines, typically spread by beefy podcast bad boy Joe Rogan. This happens just a week after fellow protestor Neil Young rejoined the streaming service.

Mitchell has made no comment about her music returning to Spotify. Back in 2022, Mitchell wrote in a statement that “irresponsible people are spreading lies that are costing people their lives. I stand in solidarity with Neil Young and the global scientific and medical communities on this issue” of the COVID vaccine, as published by Pitchfork.

Young returned to Spotify on the grounds that Joe Rogan’s podcast is no longer exclusive to the platform, as it now appears on YouTube, Apple Podcasts and Amazon Music. "My decision comes as music services Apple and Amazon have started serving the same disinformation podcast features I had opposed at Spotify," he wrote in a blog post that may have been deleted since being published. The singer also noted that fans would have nowhere to go if he pulled his music from each of the above platforms.

Beyond the obvious reasons, Young and Mitchell had a personal stake in combating medical misinformation. Both musicians were victims of polio, a disease that was wiped out in North America thanks to vaccines.

Joni Mitchell has been experiencing something of a career resurgence in the past few years. She started playing live again in 2022, after an aneurysm in 2015 left her unable to perform. The singer even performed at this year’s Grammys. As for Rogan, he recently signed a new $250 million deal with Spotify to continue his various podcast ventures.

Samsung announced pricing and availability details for its 2024 TV lineup on Thursday, and it's rolled out a fairly unique deal to entice pre-orders: If you order one of its latest sets between now and April 11, it'll throw in a bonus 65-inch 4K TV for no extra cost. The offer applies to the company's new OLED TVs (the S90D and S95D), 4K LED TVs (the QN85D and QN90D), 8K LED TVs (the QN800D and QN900D) and Frame TVs. It's available at several retailers, including Samsung.com, though you can get an extra $100 off each set at Amazon if you're a Prime member or Best Buy if you subscribe to that shop's My Best Buy Plus service. At the former, the deal comes as part of the retailer's wider Big Spring Sale event.

As for what's new with these sets, Samsung says the high-end S95D OLED TV uses anti-glare technology to hold up better in brightly-lit rooms, while the step-down S90D can reach higher brightness levels than last year's model. The aesthetics-focused Frame TV can now drop to a lower 60Hz refresh rate to conserve energy while displaying artwork, and the QN90D has an updated processor. And while most people don't need to splurge for an 8K TV, both the QN800D and top-end QN900D promise a few upscaling and motion-enhancing features based on AI.

It's an appealing promo, but there are some caveats to keep in mind before you buy. The bonus TV in question is the Samsung TU690T, an entry-level model from 2022. Though we haven't tested it ourselves, other reviews say that it can't get very bright and provides a mostly basic image. It lacks a local dimming feature to improve contrast, it's limited to a 60Hz refresh rate and it only has two HDMI ports, neither of which are HDMI 2.1. As of this writing, the 65-inch model is available for $480 at Best Buy.

It's also worth remembering how the pricing cycle of the TV market usually works. We'll have to wait for reviews to see just how improved Samsung's newest TVs are, but for the most part, they don't look to be massive upgrades over their predecessors from last year. The S95D's anti-glare tech may be the most meaningful change in practice.

Most of those 2023 TVs, meanwhile, are still available for significantly lower prices. Last year's excellent S90C OLED, for example, is now going for $1,298, which is $700 less than its 2024 equivalent. The new Frame TVs are an exception right now, though we've seen multiple discounts on last year's model in recent months. In general, the best times to buy a TV are still the holiday sales period and right about now, when new models are introduced and still-great older TVs fall in price until they're discontinued.

We highlight last year's S90C and QN90C TVs in our gaming TV buying guide, and we've previously recommended the Frame TV for those who are willing to trade some picture quality for a classier design. 

With all of that said, a free TV is a free TV. If you're dead-set on getting one of Samsung's latest and just want a large screen for, say, a guest room or office, this deal should sweeten the pot.

Companies don’t need to make huge updates to their wireless earbuds across generations. Sometimes, making a great set more reliable and adding features that extend their lifespan are upgrades enough. That’s what Sennheiser has done for the Momentum True Wireless 4 ($300). The company’s fourth-generation earbuds retain the excellent sound quality I’ve come to expect from Sennheiser along with rebuilt Bluetooth tech, higher-resolution sound, support for Bluetooth LE Audio and a tool for battery longevity. But, not everyone will reap all of the benefits I encountered during my Momentum True Wireless 4 review.

Momentum True Wireless 4: Design

The Momentum True Wireless 4 is identical in appearance to the Momentum True Wireless 3, with the only difference being a new copper/black color option alongside the existing silver/black and silver/white versions. Also, you’ll now get a fourth, extra-small, set of ear tips and the company still includes three sizes of stabilizer arcs to help you get an ideal fit. Sennheiser’s Smart Control app has a fit test too, so you’ve got help there. The company has also upgraded the dust and moisture protection here with an IP54 rating, so they now withstand fine debris in addition to water spray.

There are, however, some important changes inside the Momentum True Wireless 4. That includes an update to Qualcomm’s S5 Sound Gen 2 platform with Snapdragon Sound. Part of the Bluetooth overhaul I mentioned is a redesigned antenna, which makes this fourth-gen set of wireless earbuds more reliable. Users had reported issues with dropouts and the companion app failing to recognize the Momentum True Wireless 3, so Sennheiser is clearly addressing those issues here.

Software and features

Like with recent Sennheiser audio gear, the company’s Sound Control app is where you access all of the settings and customization options for the Momentum True Wireless 4. The main interface gives you quick access to battery percentages, Bluetooth connections, personalized sound, ANC settings, transparency level, reconfiguring touch controls, fit test and Sound Zones. That last feature allows you to automate changes to audio settings like ANC and transparency on your location. You can set up to 20 of these “zones” for places like home, work and the gym. Of course, you have to give the app permission to monitor your whereabouts to use this.

Sennheiser has taken steps to future-proof these flagship earbuds – ensuring they last for the next few years, at least. First, they support Bluetooth 5.4, which is ready for LE Audio and Auracast. Those items aren’t available on the Momentum True Wireless 4 just yet, but Sennheiser is planning an update this spring that will deliver features like broadcast audio, audio sharing and assisted listening.

If you have a recent premium Android phone, the inclusion of Snapdragon Sound will come in handy for increased audio quality. The Qualcomm processor in those devices can muster what Sennheiser calls “flawless” lossless audio when streaming from a compatible music service. There are two settings here: high resolution at 24-bit/96kHz via aptX Adaptive and lossless at 16-bit/44.1kHz with aptX Lossless.

The final quality-of-life update concerns the battery. In order to maintain better performance over time, Sennheiser added a battery protection mode that stops the buds from charging past 80 percent. This is important since earbud batteries are almost never replaceable and preventing them from overcharging will extend its lifespan. It’s nice to see the company making a product last longer, which will also have environmental impacts.

Momentum True Wireless 4: Sound quality

Sennheiser has a longstanding reputation for great sound quality and the Momentum True Wireless 4 continues that tradition. I couldn’t detect a huge difference between the Momentum True Wireless 4 and its predecessor, though, despite the company saying this year’s model has “evolved tuning” that includes things like “smoother treble response, extensive bass and effortless midrange.” And that’s just fine because the Momentum True Wireless 3 already sounded amazing.

There’s still great detail and clarity here, combined with a warm, inviting sound profile that’s enjoyable for hours on end. Even though the bass is boomy and punchy when a song like Incendiary’s “Lie of Liberty” demands it, the low-end tone never overpowers. And you can easily hear the texture of the distorted guitars, clanging hits on the ride cymbal and other subtleties on that bombastic hardcore track. Shift over to something more mellow like Charles Wesley Godwin’s Apple Music Sessions and the level of detail envelopes you even more. Those songs are also available in Dolby Atmos, so they really allow the Momentum True Wireless 4 to shine.

If the stock tuning doesn’t suit you, you can adjust a 5-band EQ and save any custom presets. The app also offers Sound Personalization, which tunes the audio to your listening preference via a quick test. The Momentum True Wireless 4 sounded great out of the box and I left the tuning untouched except for a bit of due diligence.

Android users can take advantage of the increased audio quality I mentioned earlier. There is a noticeable difference in the sound, especially in the finer details, but whether it’s “better” depends on your preferences. Of course, that higher-resolution playback will impact battery life and you’ll need a specific streaming plan (like Tidal’s Hi-Fi or Hi-Fi Plus options) or locally stored files to use what Snapdragon Sound offers in the first place.

iPhone owners shouldn’t feel left out as Apple’s AAC streaming also sounds great on the Momentum True Wireless 4. It’s aided by the fact that Apple Music’s audio quality is superior to other services, especially if the tunes are available in Dolby Atmos.

ANC performance

Like its predecessor, the Momentum True Wireless 4 has an adaptive ANC setup that automatically adjusts to changes in your environment for a more “immersive listening experience.” Sennheiser didn’t point out any differences in its noise-canceling setup on this new model and I didn’t notice any discernible improvement or decline. The ANC works just fine in most settings, but like most earbuds and headphones, it struggles with sounds like human voices. I also found that it’s not as robust as the best buds from Bose and Sony with some sources of constant noise, like white noise machines and noisy fans.

Call quality

Sennheiser uses six microphones to handle calls on the Momentum True Wireless 4. Overall quality is good, but not pristine, as long as you’re in a quiet spot. Constant noise like a raucous fan comes across as a nondescript hum, but it’s still noticeable. Transparency mode helps a bit during calls, if only to let you be aware of your surroundings. It has a natural sound compared to other earbuds, but doesn’t pipe in your voice, so the end result isn’t as good as Apple’s AirPods Pro.

Momentum True Wireless 4: Battery life

The Momentum True Wireless 4’s battery is rated to last seven hours with ANC on, but you can extend that 30 minutes by disabling it. During my tests, which consisted of mostly ANC listening at around 70-percent volume with a few calls using transparency mode, I easily hit the seven-hour mark. Factor in the case, which supports wireless charging, and you can expect up to 30 hours of playback on the go. There's also a wireless quick-charge feature with the battery protection mode that gives you an hour of use in just eight minutes.

The competition

The leader of the pack is still Sony’s WF-1000XM5. While the Momentum True Wireless 4 has the edge in terms of sound quality, Sony’s earbuds offer better noise-canceling and a host of handy features. Tools like Speak-to-Chat automatic pausing and DSEE Extreme audio upscaling cannot be overlooked. Sony also provides the ability to automatically change sound settings based on your location like Sennheiser does, so you don’t have to sacrifice that feature. The WF-1000XM5 debuted last July, which means you can find them on sale often. They’re currently going for $278, $22 less than the Momentum True Wireless 4.

Wrap-up

No new design? No problem. Sennheiser has made enough upgrades to the Momentum True Wireless 4 to make it a compelling entry in a growing line of stellar-sounding earbuds. Sound quality is great as always, and that’s the biggest selling point for me. Combine that with the higher-resolution audio on Android, forward-facing features and solid battery life, and this model checks a lot of boxes for a flagship set of buds. Sure, ANC could be better and some folks will yearn for spatial audio, but just because the Momentum True Wireless 4 is superb in some areas doesn’t mean it’s perfect.

Qualcomm is said to have new Arm-based laptops of its own in the pipeline, while consumer versions of the new Surface Pro 10 and Surface Laptop 6 that run on the Snapdragon X Elite chipset are believed to be on the way. While that in the past would have meant the makers of x86- and x64-based Windows software needing to port their apps, Qualcomm sought to assure game developers that their titles will run just fine out of the box on any unannounced Snapdragon X Elite systems that just happen to be coming up.

At the Game Developers Conference, Qualcomm engineer Issam Khalil told the audience that the computers will use emulation to run many x86 and x64 games at nearly full speed without the need to tweak the code or change any assets. According to The Verge, Khalil explained that games are typically bottlenecked by the graphics processing unit, and emulation doesn't impact GPU performance. As such (save for some CPU cost when a block of code in a game runs through its emulation process for the first time), Qualcomm suggests many titles will perform just fine.

There are some caveats. Certain games simply won't work through emulation, particularly those using kernel-level anti-cheat tech. However, Qualcomm has been testing its emulation with the top games on Steam and appears convinced that its tech should be able to handle most games.

Otherwise, Khalil told developers that they have two other options for running their games on Snapdragon-based Windows machines. They can fully port their titles to native ARM64 for optimal CPU performance and power usage. Alternatively, Qualcomm will support hybrid ARM64EC apps, in which Windows libraries and Qualcomm’s drivers run natively, but the other parts of the software are emulated. This is said to deliver “near-native” performance.

If Qualcomm can actually pull off this emulation trick as promised, it'll be an impressive move, and it could ultimately help Arm-based Windows laptops offer a blend of strong performance and better power efficiency than x86 Intel-based machines. However, the proof is in the pudding. Qualcomm hasn't had a terrific track record of x86/x64 emulation thus far. In fact, senior editor Devindra Hardawar criticized the Arm-based Surface Pro 9 for its poor Windows emulation.

So far, Apple has arguably been the most successful company at emulating x86 software on its Arm-based M-series chips with the help of its Rosetta 2 translation layer. One key point to bear in mind here is that Apple has total control over the entire ecosystem, as PC Gamer notes, including the hardware and operating system. As such, Apple can perhaps better optimize the emulation process than other companies that provide fewer parts of the equation, such as Qualcomm with its GPUs and CPUs.

Meditation is often touted as a mental cure-all, purported to help with stress, sleep, mood, focus and even certain medical conditions. I’ve been meditating most of my adult life. I’ve done silent retreats. I’ve been formally trained in various techniques. I’ve had someone in my contacts list who I referred to as a “guru.” So I feel I’m relatively qualified to give some bad news: Meditation won’t fix your life, despite what David Lynch says. However, there’s also some good news: Despite not actually being a cure-all for everything bad in the universe, meditation can certainly take the edge off.

This is where meditation apps can come into play. Of course, practicing mindfulness doesn’t require an app; people have been doing it for thousands of years, with nary a smartphone in sight. But mindfulness apps can be useful in a number of ways. They provide access to all kinds of guided meditations to suit different styles. Some even offer social connections, which can motivate you to keep up your practice via the magic of peer pressure. They are also particularly well-suited to beginners, with many of them offering a free trial. With all of this in mind, I downloaded some of the most popular meditation apps and set about sitting calmly on a comfortable chair to test them out. What follows is a comparison aimed at real people just looking to squeeze a bit more joy and relaxation out of daily life.

How we tested meditation apps

Every brain is different, so I did not rate these apps based on if they sync up with my preferred meditation style. First and foremost, I looked for apps that cater to various methods and those that offer guided meditations that go beyond what’s free on YouTube. All of the items on this list are available on both Android and iOS, so you won’t have to worry about something being only for iPhone owners.

Of course, there’s lots of free stuff out there, from podcasts and videos on YouTube to audio tracks on streaming services. You can even find guided breathing sessions on an Apple Watch or Fitbit, as well as meditations in Fitness+, Samsung Health or any number of workout video providers. For this guide, I focused on apps that stood out in some way. I liked apps with huge libraries of guided meditations and those that offer additional mindfulness activities, like yoga routines. I also looked for easy-to-use apps with well-designed layouts. You don’t want to start your meditation journey with a clunky app that actually increases anxiety.

The most important thing with meditation is to keep doing it, so I awarded points for clever gamification elements, simple social network integration and anything else that encourages repeat visits. Finally, I considered extra features that set an app apart from the glut of competitors out there. For example, some meditation apps offer novel ways to track your progress, access to yoga routines and a whole lot more.

At the end of the day, each of these apps has its strengths. But if installing an app or using a device is not how you prefer to meditate, you can always turn off your phone and find a quiet room or environment. For those of us who need a little help from a digital guru, though, here are our favorite apps for meditation.

Other meditation gear we tested

Brain-tracking wearables have been around for years, but there are some newer devices that have been tailor-made for meditators. These gadgets track the brain during meditations and offer real-time feedback. It’s a real boon for the data-obsessed, but also a real bank account drainer, with some gadgets costing thousands of dollars. I took two of the more-popular options for a spin to see what they’d make of my brain.

Sens.ai Neurofeedback System

Sens.ai is a weird contraption that not only claims to track brainwaves, but gives real-time feedback to “teach” people how to meditate and enter a flow state. The device involves a giant headset that’s stuffed with brainwave sensors that detect beta, alpha, theta and gamma waves, in addition to heart-rate sensors. It also comes with a truly bizarre companion gadget that uses light stimulation (transcranial photobiomodulation) to keep an eye on focus and attention levels. The whole thing is combined with an app that keeps track of dozens of data metrics and allows access to various guided meditations.

I’m as surprised as you to say that this thing appears to work, with some caveats. It’s uncanny how well it monitors the brain during meditations. If I got lost in a thought spiral about lasagna at six minutes in, sure enough, there would be a dip in analytics at the six-minute mark. It’s also fairly easy to use, despite a process that involves wetting a number of electrodes. As magical as the accurate brain-tracking seems to be, however, I wasn’t as keen on the actual training portion, which often involves staring at a screen throughout the entirety of the practice. It’s also not for the financial faint of heart, as the Sens.ai device costs $1,500.

NeoRhythm Omnipemf

NeoRhythm’s Omnipemf is another wearable to help people get into that ever-elusive flow state. It doesn’t track your brain, but rather floods it with electromagnetic fields at specific frequencies to make it more susceptible to meditation and focus. This is supposed to prime your brain for the meditative state and, in theory, make it easier to capture that zen. However, I didn’t get much from it, other than a placebo-esque buzzing in my head.

To use it, you simply pop on the wearable and go about your day. You aren’t tied to an app, so you can meditate in whatever way you like. There are multiple modes that go beyond meditation, as this thing is supposed to help with focus, pain relief and sleep. I’d wait for some peer-reviewed studies, however, before buying this.
