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 Fitbit Ionic works fine as a Fitbit tracker, but despite being more expensive than our picks or the Apple Watch Series 1, it lacks many smartwatch functions you’d hope to have. It passes notifications from your phone to the watch, but you can only respond to some of them (with only five quick reply lines); and dismissing them (either one by one or as a group) involves annoyingly hard presses and long scrolls. Syncing music files and offline Pandora playlists requires you to use a desktop app, which is laborious. Two Wirecutter writers who tested the Ionic also had trouble setting it up to work with their Android phones (a 2015 Moto X Pure and a 2016 Samsung Galaxy S7) and had to perform significant troubleshooting to get their data to sync. The Ionic’s battery life, even while using GPS for outdoor exercise tracking, is its most impressive feature, lasting at least five days in one test and nearly seven days in another. The Ionic is most useful to Fitbit enthusiasts who want to track outdoor exercise without bringing a phone; it’s not a good option if you’re looking to deal with incoming information.
The TicWatch E uses outdated processors and arrives very late in the lifespan of this version of Wear OS—with a new Qualcomm chip arriving in early September, there’s not a compelling reason to invest in an Android smartwatch from a lesser-known vendor right now. Beyond that, although it packs in a lot of features for less than $150, including onboard GPS, a heart-rate monitor, and a light-adjusting display, the TicWatch E looks and feels toylike, with an all-plastic body, matte silicone strap, and undistinguished look. It also has a single, non-turning button, which makes it less usable with the latest Wear OS interface. It runs Wear OS fairly well on its budget-minded processor, but Wear OS running even at its intended responsiveness is still not that exciting. The TicWatch E is not a bad budget entry as far as Android Wear watches go, but a better budget smartwatch, probably from the TicWatch’s own maker, is likely in the making.

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.
We test every new smartwatch to gauge its design and comfort. If it’s not stylish and comfortable enough to get you from an early morning workout to the office to a night out, you probably won’t wear it every day. Most smartwatches are also fitness trackers, so we put all of its sensors to the test, from step counts to heart rate to GPS (when applicable).
