Samsung Gear S3 Frontier: Until we see what Google can pack into a smartwatch with its long-awaited Pixel Watch, the best smartwatch for Android users is the Samsung Gear S3 Frontier. It pretty much has everything a user with an Android phone needs in a smartwatch - GPS, heart rate monitor, water resistance, near field communications, an always-on digital display, messaging alerts and app support. I don’t see a real need to opt for the 3G version yet, which would untether you from your phone completely but adds around $100 to the price. ($549)
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.
Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
