Fitness Trackers

A fitness tracker stays on your wrist day and night, recording heart rate, sleep and movement, and shows what it found in an app on your phone instead of on a screen of its own. Ours is the WHOOP 5.0, sold with a 12-month WHOOP Peak membership. It tracks sleep, strain, recovery and stress, lasts 14+ days per charge and is water resistant to 10 m.

The WHOOP app only works with an active membership, so check what happens after the first year before you buy. If you would rather wear a ring, the Gabit rings are under smart rings, and watches with a display are in smart watches.
