Samsung’s foray into wearables includes premium devices like the Galaxy Watch 3 and more budget-friendly trackers like the Galaxy Fit. Since the Galaxy Gear and Active, however, Samsung watches have evolved to include more fitness and health monitoring tools. With the Galaxy Watch Active2, for instance, you get auto-detection for workouts, heart-rate tracking, and whole-day battery life. The new Galaxy Watch 3, on the other hand, boasts of an ECG app, SpO2, and VO2 monitoring, plus the ability to respond to texts and make and answer calls. It comes in a premium build, too, and is water-resistant up to 50 meters.
