Just a few years ago, the case for smartwatches wasn’t clear. Today, the wearable world is filled with various high-quality options, and a few key players have muscled their way to the front of the pack. Chances are, if you’re reading this guide, you’ve probably already decided that it’s time to upgrade from a standard timepiece to a smartwatch. Maybe you want to reach for your phone less throughout the day, or maybe you want to stay connected in a more discrete way. The list of reasons why you may want a smartwatch is long, as is the list of factors you’ll want to consider before deciding which to buy.

What to look for in a smartwatch

Compatibility

Apple Watches only work with iPhones, while Wear OS devices play nice with both iOS and Android. Smartwatches made by Samsung, Garmin, Fitbit and others are also compatible with Android and iOS, but you’ll need to install a companion app.

The smartwatch OS will also dictate the type and number of on-watch apps you’ll have access to. Many of these aren’t useful, though, making this factor a fairy minor one in the grand scheme of things.

Price

The best smartwatches generally cost between $300 and $400. Compared to budget smartwatches, which cost between $100 and $250, these pricier devices have advanced fitness, music and communications features. They also often include perks like onboard GPS, music storage and NFC, which budget devices generally don’t.

Some companies make specialized fitness watches: Those can easily run north of $500, and we’d only recommend them to serious athletes. Luxury smartwatches from brands like TAG Heuer and Hublot can also reach sky-high prices, but we wouldn’t endorse any of them. These devices can cost more than $1,000, and you’re usually paying for little more than a brand name and some needlessly exotic selection of build materials.

Battery life

Battery life remains one of our biggest complaints about smartwatches, but there’s hope as of late. You can expect two full days from Apple Watches and most Wear OS devices. Watches using the Snapdragon Wear 3100 processor support extended battery modes that promise up to five days on a charge — if you’re willing to shut off most features aside from, you know, displaying the time. Snapdragon’s next-gen Wear 4100 and 4100+ processors were announced in 2020, but only a handful of devices – some of which aren’t even available yet – are using them so far. Other models can last five to seven days, but they usually have fewer features and lower-quality displays. Meanwhile, some fitness watches can last weeks on a single charge.

A few smartwatches now support faster charging, too. For example, Apple promises the Series 7 can go from zero to 80 percent power in only 45 minutes, and get to full charge in 75 minutes. The OnePlus Watch is even speedier, powering up from zero to 43 percent in just 10 minutes. (Mind you that turned out to be one of the only good things about that device.)

Communication

Any smartwatch worth considering delivers call, text and app alerts to your wrist. Call and text alerts are self explanatory, but if those mean a lot to you, consider a watch with LTE. They’re more expensive than their WiFi-only counterparts, but data connectivity allows the smartwatch to take and receive calls, and do the same with text messages, without your phone nearby. As far as app alerts go, getting them delivered to your wrist will let you glance down and see if you absolutely need to check your phone right now.

Fitness tracking

Activity tracking is a big reason why people turn to smartwatches. An all-purpose timepiece should log your steps, calories and workouts, and most of today’s wearables have a heart rate monitor as well.

Many smartwatches also have onboard GPS, which is useful for tracking distance for runs and bike rides. Swimmers will want something water resistant, and thankfully most all-purpose devices now can withstand at least a dunk in the pool. Some smartwatches from companies like Garmin are more fitness focused than others and tend to offer more advanced features like heart-rate-variance tracking, recovery time estimation, onboard maps and more.

Health tracking on smartwatches has also seen advances over the years. Both Apple and Fitbit devices can estimate blood oxygen levels and measure ECGs. But the more affordable the smartwatch, the less likely it is that it has these kinds of health tracking features; if collecting that type of data is important to you, you’ll have to pay for the privilege.

Music

Your watch can not only track your morning runs but also play music while you’re exercising. Many smartwatches let you save your music locally, so you can connect wireless earbuds and listen to tunes without bringing your phone. Those that don’t have onboard storage for music usually have on-watch music controls, so you can control playback without whipping out your phone. And if your watch has LTE, local saving isn’t required — you’ll be able to stream music directly from the watch to your paired earbuds.

Always-on displays

Most flagship smartwatches today have some sort of always-on display, be it a default feature or a setting you can enable. It allows you to glance down at your watch to check the time and any other information you’ve set it to show on its watchface without lifting your wrist. This will no doubt affect your device’s battery life, but thankfully most always-on modes dim the display’s brightness so it’s not running at its peak unnecessarily. Cheaper devices won’t have this feature; instead, their screens will automatically turn off to conserve battery and you’ll have to intentionally check your watch to turn on the display again.

NFC

Many smartwatches have NFC, letting you pay for things without your wallet. After saving your credit or debit card information, you can hold your smartwatch up to an NFC reader to pay for a cup of coffee on your way home from a run. Keep in mind that different watches use different payment systems: Apple Watches use Apple Pay, Wear OS devices use Google Pay, Samsung devices use Samsung Pay and so forth.

Apple Pay is one of the most popular NFC payment systems, with support for multiple banks and credit cards in 72 different countries, while Samsung and Google Pay work in fewer regions. It’s also important to note that both NFC payment support varies by device as well for both Samsung and Google’s systems.

Engadget Picks

Best overall: Apple Watch

Cherlynn Low / Engadget

The Apple Watch has evolved into the most robust smartwatch since its debut in 2015. It’s the no-brainer pick for iPhone users, and we wouldn’t judge you for switching to an iPhone just to be able to use an Apple Watch. The latest model, the Apple Watch Series 7, has solid fitness-tracking features that will satisfy the needs of beginners and serious athletes alike. It also detects if you’ve fallen, can carry out ECG tests and measures blood oxygen levels. Plus, it offers NFC, onboard music storage and many useful apps as well as a variety of ways to respond to messages.

The main differences between the Series 7 and the Series 6 that preceded it are the 7’s larger display, its overnight respiratory tracking and faster charging. The slight increase in screen real estate allows you to see things even more clearly on the small device, and Apple managed to fit a full QWERTY keyboard on it to give users another way to respond to messages. The faster charging capabilities are also notable – we got 10 percent power in just 10 minutes of the Watch sitting on its charging disk, and it was fully recharged in less than one hour.

While the $399 Series 7 is the most feature-rich Apple Watch to date, it’s also the most expensive model in the Watch lineup, and for some shoppers there might not be clear benefits over older editions. Those who don’t need an always-on display, ECG or blood oxygen readings might instead consider the Apple Watch SE, which starts at $279.

We actually regard the Watch SE as the best option for first-time smartwatch buyers, or people on stricter budgets. You’ll get all the core Apple Watch features as well as things like fall detection, noise monitoring and emergency SOS, but you’ll have to do without more advanced hardware perks like a blood oxygen sensor and ECG monitor.

Best budget: Fitbit Versa 2

Dropping $400 on a smartwatch isn’t feasible for everyone, which is why we recommend the Fitbit Versa 2 as the best sub-$200 option. It’s our favorite budget watch because it offers a bunch of features at a great price. You get all of these essentials: Fitbit’s solid exercise-tracking abilities (including auto-workout detection), sleep tracking, water resistance, connected GPS, blood oxygen tracking and a six-day battery life. It also supports Fitbit Pay using NFC and it has built-in Amazon Alexa for voice commands. While the Versa 2 typically costs $150, we’ve seen it for as low as $100.

Best for Android users: Samsung Galaxy Watch 4

David Imel for Engadget

Samsung teamed up with Google recently to revamp its smartwatch OS, but that doesn’t mean Tizen fans should fret. The Galaxy Watch 4 is the latest flagship wearable from Samsung and it runs on WearOS with the new One UI, which will feel familiar if you’ve used Tizen before. Also, the watch now comes with improved third-party app support and access to the Google Play Store, so you can download apps directly from the watch.

We like the Galaxy Watch 4 for its premium design as well as its comprehensive feature set. It has a 3-in-1 biometric sensor that enables features like body mass scanning, bloody oxygen tracking and more, plus it has a plethora of trackable workout profiles. Both the Galaxy Watch 4 and the Watch 4 Classic run on new 5nm processors and have more storage than before, as well as sharper, brighter displays. They both run smoothly and rarely lag, but that performance boost does come with a small sacrifice to battery life: the Galaxy Watch 4 typically lasted about one day in our testing, which while not the best, may not be a dealbreaker for you if you plan on recharging it every night.

Fashion-forward options

Fossil

Yes, there are still companies out there trying to make “fashionable” smartwatches. Back when wearables were novel and generally ugly, brands like Fossil, Michael Kors and Skagen found their niche in stylish smartwatches that took cues from analog timepieces. You also have the option to pick up a “hybrid” smartwatch from companies like Withings and Garmin – these devices look like standard wrist watches but incorporate some limited functionality like activity tracking and heart rate monitoring. They remain good options if you prefer that look, but thankfully, wearables made by Apple, Samsung, Fitbit and others have gotten much more attractive over the past few years.

Ultimately, the only thing you can’t change after you buy a smartwatch is its case design. If you’re not into the Apple Watch’s squared-off corners, all of Samsung’s smartwatches have round cases that look a little more like a traditional watch. Most wearables are offered in a choice of colors and you can pay extra for premium materials like stainless steel. Once you decide on a case, your band options are endless – there are dozens of first- and third-party watch straps available for most major smartwatches, allowing you to change up your look whenever you please.

What better way to show someone you love them than getting them a gadget that they can wear on their person all day? Okay, maybe there are plenty of better ways, but a wearable can not only convey how much you care, but it can also help the user take better care of themselves.

Our list of the best wearables includes not only obvious things like smartwatches and fitness trackers, but also a touch-sensitive backpack that will let the hiker on your list keep their hands free while trekking through the mountains. Though the typical price here of about $200 to $300 might be steep for some, it might be a good range for those looking for something that a few friends can all chip in on. But we’ve also included budget-friendlier options if you prefer.

Apple Watch SE

Will Lipman Photography for Engadget

A smartwatch is a great gift for anyone that’s trying to stay on top of their busy schedules, keep tabs on their health or remain connected without having to look at their phone every 30 seconds. The Apple Watch SE is a solid choice for any first timer — it has all of the core features of the more-premium Series 7, but costs significantly less. Your loved one will be able to use it to track their workouts and sleep while getting their iPhone alerts and messages on their wrist. The watch will also detect if they’ve fallen and alert the user’s emergency contacts, not to mention warn the wearer of any heart rate irregularities. Of course, no smartwatch is meant to replace a consultation with a doctor, so think of it more as a way to get some data than as a tool for diagnosis.

If you believe your friend could benefit from a bigger screen, longer battery life, ECG readings and an always-on display, the $400 Series 7 is a better choice. But you’ll have to decide if those main differences are worth the premium.

Samsung Galaxy Watch 4

The Apple Watch is the best smartwatch around. Unfortunately it won’t work with Android phones. Thankfully, there are plenty of options for those over in Google-land, and the best of them is the Galaxy Watch 4. It runs the new Wear OS co-engineered by Samsung and Google, marrying an intuitive side-scrolling interface and great health-tracking with a plentiful third-party app library. That means your friend can reply to your texts from their wrist, get updates on their cab rides or takeout orders, track their calorie intake or log workouts through their favorite apps. Those who are into their physical and muscular composition will also appreciate the Watch 4’s body fat-scanning tool.

If the person you’re shopping for prefers a more classic-looking timepiece and doesn’t mind a chunkier device, they might enjoy the Galaxy Watch 4 Classic. It features a spinning bezel that lets the user whiz through widgets quickly and easily, and the etchings on the frame lend a traditional look to the smartwatch.

Fitbit Charge 5

Those looking for something with a lower profile will prefer a Fitbit band. Despite its relatively small size, the Fitbit Charge 5 packs a ton of hardware including a heart rate monitor, onboard GPS and an electrodermal activity (EDA) sensor. Altogether, it can help your loved one track their pulse, fitness and even stress levels. Fitbit also has one of the more insightful sleep-logging tools around, using cardio readings to determine if they’ve entered deep, REM or light sleep zones.

The company also made its touchscreen full-color on the Charge 5, which is a vast improvement over the last model’s greyscale version. This does diminish battery life, but the Charge 5 still manages to last up to seven days (though, that drops to two with the display set to Always On).

Fossil Gen 6

Will Lipman Photography for Engadget

For the Android smartwatch user who wants a little more fashion cred on their wrist, the Fossil Gen 6 is a worthy option. These are the company’s first to run the new Wear OS, but with some custom watch faces and tweaks for health-tracking. They have bright, crisp 1.28-inch AMOLED screens and offer continuous heart-rate monitoring, as well as a blood oxygen sensor.

Battery life has always been a big shortcoming of smartwatches, and Fossil is attempting to make up for that by offering fast charging on the Gen 6. It promises you can get up to 80 percent in 30 minutes, so your giftee doesn’t have to spend too long waiting around for their watch to power back up. And since this is a Fossil wearable, there are plenty of attractive strap and case options that will suit your loved one’s tastes.

Amazon Echo Frames

Will Lipman Photography for Engadget

Not all wearables are watches: there’s been a recent surge in speaker-glasses hybrid devices. The Amazon Echo Frames are the most comfortable, though. Like the Bose Frames and Razer’s Anzu, they offer open-ear style speakers built into the arms of the eyewear so that the wearer can hear what’s playing on their computer or phone without blocking out the rest of the world. Amazon’s version also offers easy access to Alexa, so the user can get hands-free help with setting timers or turning on their smart lights.

The Echo Frames can be fitted with prescription lenses and come in an inoffensive style that should fit most faces (there’s only one size available). Those who don’t need glasses can also opt for blue-light filtering lenses or shades instead. If you know someone who wants to listen to music or their favorite YouTube livestream at work, while still being able to hear when their boss calls them into the office, the Echo Frames are a good option.

Withings Steel HR

Withings

Some diehard watch aficionados don’t like the idea of a black mirror staring up at them when smartwatch batteries die, but still want a timepiece that can track basic health metrics. For these folks, the Withings Steel HR is an attractive, well-rounded product. It has a traditional analog watch face with a tiny round black-and-white screen that shows step counts and small status indicators. A sub-dial displays progress towards the wearer’s daily move goal, and runners can link the watch to their phone’s GPS to map their routes.

The device’s onboard heart rate and blood oxygen sensors help the user gauge their cardio performance, and swimmers or divers will appreciate the water resistance of up to 50 meters. Best of all, since this doesn’t have a large, battery-draining screen, it can last up to 25 days on a charge.

Garmin Forerunner 55

The hardcore runner or marathoner in your life will most likely have heard of Garmin. The company is known for its GPS and heart rate monitors, and athletes swear by their running watches. The Forerunner 55 is a great device for those looking for something that excels at sports-tracking with long-lasting battery. It’ll last up to two weeks, while monitoring the user’s respiration, heart rate, step count and more. The wearer can also get basic notifications, music playback controls and apps on the watch.

But it’s Garmin’s robust sports features that will win your giftee over. These include comprehensive run coaching with cadence alerts, pace suggestions, estimated finish time and recovery guides. The Forerunner 55 also tracks stress and menstrual cycles and offers emergency contact tools when the wearer feels unsafe.

Samsonite x Google Konnect-i backpack

Who knew a backpack could be smart? The Samsonite Konnect-i bag features touch-sensitive fibers woven into its strap to enable Google’s Jacquard technology. This lets the wearer tap and swipe on the surface to do things like answer phone calls, play or pause music and more by connecting to their phone. For those who need to pay attention to their commute instead of fumbling around with a phone when they’re on the go, the Konnect-i backpack can keep their hands free and eyes alert. If you have the money to spare and want to give your friend a serious style upgrade, Google also teamed up with Saint Lauren on a $1,150 branded version.

Miniaturization has made smart watches possible, even for the DIY maker to tinker with. For those just getting to grips with basic digital electronics, it can be daunting, however. For those just starting out, [陳亮] put together a handy guide to building the core of an Arduino-based watch.

The writeup starts at the beginning, going over the basic hardware requirements for a smart watch. This involves considering size, packaging and power draw, as well as the user interface. The build settles on an Arduino Pro Micro, as it uses the ATmega32U4 which eliminates secondary USB-to-serial chips, helping cut down on power consumption. A square IPS LCD display is used to display an analog-style watch face, and time is kept by a DS3231 real-time clock. A pair of small vibration sensors are used to wake the watch when the user moves their wrist to check the time.

While it doesn’t cover the final assembly into a watch-like form factor, it’s a handy guide on what it takes to build a working watch for those who are still getting their feet wet with hardware. Once you’ve got that down, it’s time to contemplate how you’ll build the sleek exterior. Naturally, a good maker has that covered, too.

The concept of a smartwatch was thrown around for a long time before the technology truly came to fruition. Through the pursuit of miniaturisation, modern smartwatches are sleek, compact, and remarkably capable for their size. Companies such as Apple and Samsung throw serious money into research and development, but that doesn’t mean you can’t create something of your own. [Electronoobs] has done just that, with this Arduino-based smartwatch build.

The brain of the watch is that hacker staple, the venerable ATmega328, most well known for its use in the Arduino Uno and Nano platforms. An FTDI module is used for USB communication, making programming the board a snap. Bluetooth communication is handled by another pre-built module, and a smartphone app called Notiduino handles passing notifications over to the watch.

This is a build that doesn’t do anything crazy or difficult to understand, but simply combines useful parts in a very neat and tidy way. The watch is impressively thin and compact for a DIY build, and has a host of useful functions without going overboard.

We’ve seen other DIY builds in this space, too – such as this ESP8266-based smartwatch. Video after the break.

Although smartwatches were designed to be an easy-to-use alternative for your smartphone, interacting with their touchscreens still requires your opposite hand to be free. So what do you do when you’re carrying a bag of groceries or holding onto a bus handle?

This is the problem a Dartmouth-led team set out to solve with WristWhirl, a smartwatch prototype that uses the wrist wearing the device as a joystick to perform common touchscreen gestures with one-handed continuous input, while freeing up the other hand for other tasks.

WristWhirl was built using a two-inch TFT display and a plastic watch strap equipped with a dozen infrared proximity sensors and a piezo vibration sensor, which is connected to an Arduino Due board. Commands are then made by moving the hand as if it were operating a joystick, while a finger pinch turns the sensors on/off to indicate the start or end of a gesture.

For starters, the team implemented four sample applications with off-the-shelf games and Google Maps to illustrate potential use cases.

Four usage scenarios for WristWhirl were tested: 1) a gesture shortcuts app was created, which allowed users to access shortcuts by drawing gestures; 2) a music player app was created, which allowed users to scroll through songs through wrist-swipes and play a selected song by double tapping the thumb and index fingers; 3) a map app was implemented for which 2D maps could be panned and zoomed depending on where the watch was held in relation to one’s body; and 4) game input, which often requires continuous input was tested, for which Tetris was played using a combination of wrist swipes, wrist extension and wrist flexion.

There are a myriad of modern ways to lock and unlock doors. Keypads, Fingerprint scanners, smart card readers, to name just a few. Quite often, adding any of these methods to an old door may require replacing the existing locking mechanism. Donning his Bollé sunglasses allowed [Dheera] to come up with a slightly novel idea to unlock doors without having to change his door latch. Using simple, off the shelf hardware, a Smartwatch, some code crunching and a Google Now app, he was able to yell “OK Google, Open Sesame” at his Android Wear smartwatch to get his apartment  door to open up.

The hardware, in his own words, is trivial. An Arduino, an HC-05 bluetooth module and a servo. The servo is attached to his door latch using simple hardware that looks sourced from the closest hardware store. The code is split in to two parts. The HC-05 listens for a trigger signal, and informs the Arduino over serial. The Arduino in turn activates the servo to open the door. The other part is the Google Now app. Do note that the code, as he clearly points out, is “barebones”. If you really want to implement this technique, it would be wise to add in authentication to prevent all and sundry from opening up your apartment door and stealing your precious funky Sunglasses. Watch a video of how he put it all together after the break. And if you’re interested, here are a few other door lock hacks we’ve featured in the past.

Take an e-ink smartwatch that's got plenty of willing customers, throw in a WiFi-connected sensor box and well, imagine the possibilities. The founders behind Pebble and Twine hope you are, because they have announced that the pair will be connectable through the latter's web-based interface. This means you'll be able to setup text notifications to your wrist when your laundry's done, when someone's at your door and plenty more mundane real-world tasks. A brief video explains how it should all go down, but try not to get too excited -- pre-orders are sadly sold out.
