To round off the Gear Sport’s positives, it has very solid battery life (almost never less than 50 percent of the battery remaining after a full day), it can play offline Spotify playlists (even for free accounts), and if you have a Samsung phone, it integrates easily with most of the apps you have installed there. The Gear Sport is easier to set up with a non-Samsung Android phone than previous versions of the Gear watch, too. It still requires the installation of at least four apps and some regular updating, but it’s not the hour-long trial-and-error of other Gear watches we’ve tested, working reliably in our testing.
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+.
The Apple Watch Series 4 is now on sale, and it's the best smartwatch you can buy right now. The redesigned device, which starts at $399 for the GPS model and $499 for the cellular version, is the best smartwatch you can buy. It has a larger display and slightly bigger case size while retaining the same rounded square design the watch is known for. Even more importantly, Apple received FDA clearance for a new electrocardiogram feature that can take a 30-second EKG and diagnose atrial fibrillation.
