For its price, the GTR 4 offers an impressive number of features. It does a good job of tracking all kinds of health and fitness metrics, from heart, sleep, and stress to your menstrual cycle, while boasting over 150 sport modes and multiband GPS. Aside from being an excellent fitness tracker, the GTR 4 is also a good smartwatch with a crisp OLED display, long battery life, and support for Amazon Alexa and turn-by-turn navigation. Even better, unlike some of its rivals, you don’t need to be locked into a particular ecosystem to take advantage of its features. The wearable is platform-agnostic, after all, making it a good investment whether you’re an Android or iOS user.
