The Sport’s built-in fitness features do a decent job of motivating you to move more, tracking a Fitbit-like set of metrics: Stairs climbed, steps taken, and minutes active. It reminds you to get up every hour or so and suggests stretches and movements you can do at your desk if you’re stuck there. While the Sport can track your movement and exercise, and start doing so automatically, it is not accurate enough for dedicated runners or cyclists (who should get a GPS running watch instead): Influential fitness gear tester Ray Maker (aka DC Rainmaker) clocked “the worst GPS track accuracy I’ve ever seen on a run” wearing the Gear Sport. We didn’t see quite the same entirely-different-street discrepancies in biking tests, but the Sport is nevertheless not a competitive training tool, providing only a rough guide to distance and speed.
The Passport is versatile in that it works with Android and iOS mobile devices. And it features the ability to make phone calls with its built-in microphone and speaker. You can use voice commands (the Passport leverages your phone's voice recognition system; such as Apple's Siri for iOS devices or Google Now for Android) to control the mobile device from the watch. And because of the analog watch face, you can easily see the time in bright sunlight.
The Moto 360 was the first round smartwatch we got our hands (or wrists) on, and the design was a standout, for us. It looks like a traditional watch and fits more comfortably than rectangular smartwatches, but still packs the full functionality of an advanced smartwatch. Like the LG G Watch and Samsung Gear Live, it runs the Android Wear OS, allowing voice commands and pushing relevant information to the wearer.
The MetaWatch M1, like the Cookoo 2 and Martian Notifier, is a basic smartwatch. It shows alerts for texts, e-mails, social media updates, calendar appointments, weather, and Caller ID, and can control your phone's music app. The notifications are configurable in terms of what you are alerted to and how: whether via a vibration or on the watch’s display. Also built in are a timer, a stopwatch, and an alarm
If you don’t need your smartwatch to look business-casual, you want more fitness and exercise features than our top pick, or you’re a Samsung loyalist, the Samsung Gear Sport is a better pick for you. (You can use the Gear Sport with non-Samsung phones, but doing so requires that you install at least four apps.) The Gear Sport handles all the casual notification and message-triage functions of a smartwatch about as well as our top pick—with the exception of voice transcription—but it adds heart-rate monitoring, GPS tracking, swim tracking, and built-in reminders to move throughout the day. It doesn’t do all of these things perfectly, but it does just enough to make for a generally useful smartwatch, with great battery life and a clever interface.
Of the scores of Wear OS by Google (also called Wear OS, and formerly Android Wear) smartwatches that function nearly the same, the Fossil Q Explorist and Fossil Q Venture are the ones we recommend for most people. Similar models that differ mainly in size and design, these two Fossil watches offer style and band options for the widest range of tastes while performing as well as (or better than) anything else out there. They handle notifications and your responses without delay, provide all-day battery life, swiftly handle voice transcription and Google Assistant questions, and provide casual fitness tracking. Their buttons and screens are responsive. They look and feel like good watches, too, which is something we think most people want from a smartwatch at this point.
My personal favorite watch for Android on the market today actually isn’t an Android Wear device, rather coming from Samsung and running atop Tizen. The Samsung Gear S3 Frontier is all the smartwatch you’ll ever need, with a sporty, circular gray design with a 1.3-inch Super AMOLED display that is the best I’ve personally ever used and is protected by Corning Gorilla Glass SR+.
I’ve worn a smartwatch almost daily for nearly five years as of this writing. I often feel that it keeps me alert to what’s happening, especially for things like texts from my wife and close friends, alarms that a parking meter is nearly expired, or reminders that dinner needs to start marinating or roasting. It has also encouraged me to get moving and take a walk when I’d otherwise stay in place. Sometimes it has made me feel rude, distracted, or overly attached to whatever little blip comes next. It has come in handy on my bike, and it has distracted me when I’m driving my car. Some of this can be better handled through settings and filters, but some of it comes from human nature.
The headline features are the new ECG monitor that unlocks the ability for serious heart health monitoring. It's been FDA cleared, so the feature can be used to detect heart rhythm irregularities - however, it's only in the US only for now. There's also a new fall detection mode that can let users access Siri to contact emergency services or a emergency contact. Apple's new smartwatch offers groundbreaking features and an improved design that makes it the standout option for iPhone owners right now.
Flaws but not dealbreakers: Wear OS, Google’s name for Android for smartwatches, still feels like a work in progress, and in our testing, the Google Assistant voice feature frequently dropped responses—though that could improve via software updates. The Q line’s button at the 3 o’clock position is easy to accidentally trigger, bringing up Google Assistant and sometimes sending it nonsense questions. Wear OS also lacks a left-handed mode to allow you to switch the watch around. On the workout front, Fossil Q watches lack a heart rate monitor, so they’re not able to detect workouts or help with pacing; and the size of these models—and most Android smartwatches, really—and the touchscreen interface make workouts more difficult to monitor and pause than with a dedicated fitness tracker.
You can also use devices that support the Google Wear operating system in conjunction with an iPhone as well as a Samsung Gear device that runs Samsung’s own Tizen operating system. But Google Wear and Tizen devices are designed to pair with smartphones using the Android OS, so you won’t get full functionality when pairing with an iPhone. For instance, some Android smartwatches carry Samsung’s smartwatch line-up and naturally enough, work best with Samsung smartphones, but are still compatible with Android-powered Huawei or Nokia phones.
