The touchscreen, button, and dial (what Apple calls the “crown”) help you zoom in and out and move between apps fairly effortlessly. With this easy navigation it’s easy to forget we’re typing on a screen slightly smaller than an Oreo. In particular, we loved Apple’s app homepage, which displays all of the apps as icons in a honeycomb-like display. You can use the touchscreen to move around, and the dial to zoom in or pan out, to precisely tap on the one you want.

The Gear S3 also offers a dual-core Exynos 7270 processor, 768MB of RAM, and 4GB of storage. The watch also features sensors such as GPS, NFC, and even optional LTE. The standout features, though, include Samsung Pay (on any smartphone) and the rotating bezel. The Gear S3 is a pretty big watch, though, coming in at 12.9mm thick with a 46mm diameter.

In 1998, Steve Mann invented, designed, and built the world's first Linux wristwatch,[15] which he presented at IEEE ISSCC2000 on 7 February 2000, where he was named "the father of wearable computing".[16] See also Linux Journal,[17] where Mann's Linux wristwatch appeared on the cover and was the feature article of LJ Issue 75. Seiko launched the Ruputer in Japan - a wristwatch computer with a 3.6 MHz processor. It was not very successful, since instead of a touchscreen it used a joystick-like device to input characters (much like high scores in arcade games), and the small screen with a resolution at 102x64 in 4 greyscales made it hard to read large amounts of text. Outside of Japan, this watch was distributed as the Matsucom onHand PC. Despite the rather low demand, the Matsucom onHand PC was distributed until 2006, making it a smartwatch with a rather long life cycle. Ruputer and onHand PC applications are 100% compatible. This watch is sometimes considered the first smartwatch since it was the first watch to offer graphics display (albeit monochrome) and many 3rd party applications (mostly homebrew).
Samsung released its Galaxy Watch, a follow-up to the Gear S3, a prior pick. The Galaxy Watch is available in 42 mm and 46 mm configurations, with either a Bluetooth-only connection or Bluetooth plus LTE from T-Mobile (at launch). The biggest update seems to be the battery life, which the company claims will last for days between charges. The Bluetooth version of the Galaxy Watch is available for $330 for the smaller version and $350 for the larger (46 mm) model; the 42 mm LTE version is available for $380 and the 46 mm is $400.
But smartwatches have the innovation advantage these days as most companies making such devices try to develop features that competitors don't have. As a result, fitness trackers have become a bit stale. And after wearing the new Charge 3 for nearly two weeks to see how well Fitbit's gentle marriage of smartwatch and tracker features turned out, it seems the form factor remains radically unchanged—but that's not a bad thing in practice.
Bottom line: If health and fitness tracking is your priority, opt for a dedicated fitness tracker that gives you basic time and date information but includes the essentials of health tracking - accelerometer and altimeter, heart rate monitor and GPS chip to track distance and location. Carefully consider your exercise habits to match them to the right fitness tracker.
Tizen is a Linux-based operating system for devices, including smartphones/tablets, in-vehicle infotainment (IVI) devices, smart TVs, laptops/desktops and other platforms. Tizen is a project within the Linux Foundation and is governed by a Technical Steering Group (TSG) composed of Samsung and Intel among others. Samsung released the Samsung Gear 2, Gear 2 Neo, Samsung Gear S, Samsung Gear S2 and Samsung Gear S3 running Tizen.[86]

But the Ionic, the first of Fitbit's devices to include an SpO2 monitor, came out more than one year ago. It's frustrating to hear about exciting features that are "coming soon," when "soon" ultimately means not weeks or months, but years. While I understand it takes time and effort to develop features like this (especially if Fitbit hopes to pursue medical device clearance or approval from the FDA in the future), I don't think Fitbit should hype features that it isn't ready to let users put to the test.
Wrist watches have been fashion accessories since they were first invented. The first generation of smartwatches were dull, chunky looking devices, more functional than fashionable. How things have changed. You can select from thousands of watch faces and even design your own. Wrist straps can be swapped out and designers have come up with clever quick-release clasps for them, knowing that the need to charge your watch regularly will see you needing to remove it quickly.
Next is the big focus on health and fitness. The Apple Watch can monitor your heart rhythm and suggest you see a doctor if it detects something irregular, it can call the emergency services you've fallen over, and it will keep you healthy by tracking your run. These potentially life saving features are a major reason people are ditching their traditional watches for an Apple Watch.
Since the early days of modern smartwatches, we’ve sought to test as many relevant models as we can and recommend the watches that do the best job of making a smartwatch convenient and useful. We test Wear OS watches by wearing them while they’re connected to Android phones. Whenever possible, we ask other people to try out our potential picks to get an idea of how others react to a watch’s size, style, interface, and other features.
Battery life and charging options: Charging your smartwatch is a hassle and the biggest downside to trading in your manually-wound or button battery-powered watch. A Fitbit Versa might last 3 - 4 days between charges, but a smartwatch like the Samsung Gear Sport or Apple Watch will need recharging every couple of days and sometimes every night if you are tapping on the screen regularly and using its apps.
But your phone will play an important part if you do get a Fitbit or Garmin device with the aim of tracking your activity. It will be the place where your health data is synced to, you can tinker with your tracking settings and review your progress. There’s also a whole ecosystem of health apps that plug into tracking devices, combining them with exercise and diet advice - MyFitnessPal, Runtastic and Strava are three of the most popular ones worth checking out.
I’ve had the Samsung Gear S3 classic for a few months now. There are lots of apps now available including a music app which allows you to save and play as many tracks as the sizeable built in memory will allow you to save to the watch. The in-built speaker is high quality for making and receiving calls and of course listening to music, but a Bluetooth headset makes all the difference.
Being able to customize the watch faces and layouts, made the Series 3 a shoo-in for our list of best smart watches. Much like you can customize the homescreen on your iPhone, you can change the layout of apps and even display the weather. While you can’t opt for third-party designs, you do have 12 different watch faces to play with. Tinker with color schemes, add or remove widgets (called “complications” on the app), and decide whether you want to have all twelve faces available on your watch (we always like having options), or cut back.
