The Samsung Gear Fit2 monitors heart rate and offers automatic activity tracking, whether walking, cycling or rowing. Its inbuilt GPS helps runners track their routes, distance and speed in real time. All information, such as calories burned, is displayed on a large 1.5” screen, which is easy to read mid-workout, which can also be customised with various faces and widgets. The device comes in two different sizes, ensuring a snug fit, and can be synced with an array of smartphones for enhanced functionality.
