But smartwatches have the innovation advantage these days as most companies making such devices try to develop features that competitors don't have. As a result, fitness trackers have become a bit stale. And after wearing the new Charge 3 for nearly two weeks to see how well Fitbit's gentle marriage of smartwatch and tracker features turned out, it seems the form factor remains radically unchanged—but that's not a bad thing in practice.
But your phone will play an important part if you do get a Fitbit or Garmin device with the aim of tracking your activity. It will be the place where your health data is synced to, you can tinker with your tracking settings and review your progress. There’s also a whole ecosystem of health apps that plug into tracking devices, combining them with exercise and diet advice - MyFitnessPal, Runtastic and Strava are three of the most popular ones worth checking out.
Bottom line: If health and fitness tracking is your priority, opt for a dedicated fitness tracker that gives you basic time and date information but includes the essentials of health tracking - accelerometer and altimeter, heart rate monitor and GPS chip to track distance and location. Carefully consider your exercise habits to match them to the right fitness tracker.
Samsung's Galaxy Watch, a Tizen OS watch (starting at $329), is our favorite smartwatch for Android users. In addition to up to four days of battery life and a great design, the Galaxy Watch offers built-in GPS, heart rate sensor, water-resistance, Samsung Pay support, plus a nifty rotating bezel for navigating the interface. You can also download music from Spotify to the watch for offline listening. However, you get far fewer apps than you would with a Wear OS watch.
