The Samsung Gear Fit is not just a fitness tracker, or a smartwatch — it's both. The device, which costs about $200, combines smartwatch features, such as call and alarm notifications, with the functions of a more traditional fitness tracker, such as the ability to track daily steps and calories burned. It even includes a heart rate monitor that works when you're at rest or exercising. But is this hybrid better than a normal tracker? I tested the device to find out.
