5 of the best wearable gadgets

Fitbit Ultra £80 fitbit.com
The Fitbit packs a lot of life-tracking into one small chunk. A super-sensitive pedometer and altimeter records your every movement and your sleep cycle, wirelessly syncing to your computer. The gadget’s one and only button tells you how active you’ve been. While it might not record your runs as accurately as a GPS fitness watch, its constant nagging might encourage you to get off the bus a stop earlier, or take the stairs, or get an extra hour’s sleep – so it could be more effective as a health-improving device. Let it form your habits, and it could make a real difference.
