The GTS 2e offers an impressive array of health monitoring tools: accurate blood oxygen saturation, sleep, all-day heart rate monitoring, and stress checks throughout the day – all clearly displayed in the Zepp companion app. Fitness monitoring is also well implemented and can keep up with the best Fitbits. It offers built-in GPS, a wide range of activity presets, automatic activity detection, and a wide range of readings for post-workout follow-up. Stats were generally on par with the similarly equipped Garmin Vivoactive 4S, and data can be automatically synced with third-party apps like Strava. It’s a shame that the PAI fitness score calculated by the Zepp app isn’t more useful. It’s meant to be an overall measure of fitness, but there’s little information on how it’s calculated or what steps you can take to improve and maintain it. The Amazfit GTS 2e is very similar in size and shape to the Apple Watch 6, but without the digital crown. Instead, the crown button on the GTS 2e is only used to unlock the watch and select the current menu option; all other controls are controlled via the touchscreen. The watch is available in black, green and purple and features a comfortable silicone band, aluminum alloy band and buckle closure. The charger is magnetic and easily attaches to the back of the device. The 1.65-inch HD AMOLED display is very bright and easy to read in all lighting conditions. The face is customizable; many additional options can be downloaded via the app, or you can create your own with your own photos. Most designs can be set to run continuously, though this comes at the expense of battery life. Setup is pretty straightforward. First, charge the watch, install the Amazfit Zepp app on your smartphone, and create an account. Scan the QR code that appears on the watch face to connect the two devices – you don’t have to enter a confirmation code, as is the case with other fitness trackers. After that, you need to perform a firmware update and the watch is ready to use. The setup is quite simple.
