WITHINGS PULSE HR TRACKER

The newest Withings tracker can monitor more than 30 sports, encompassing everything from volleyball to yoga. As with the Steel HR, there’s no GPS, so pair it to your phone for accurate outdoor run monitoring. In this set-up, it can also deliver notifications to your wrist – when someone texts, for instance. It’s clever enough to know from your movements when you’re going from deep to light sleep, so can rouse you at the optimal moment in your sleep cycle, ensuring you wake refreshed – the tracker’s alarm system (the Steel HR also has this feature) can wake you by vibrating. Battery life is this brand’s forte; in this case, up to 20 days. £120, withings.com
