The Apple Watch uses your age, gender, height and weight, in addition to the GPS in your iPhone and data from its own built-in sensors, to calculate both your resting calories and ones you burn during exercise.
The Apple Watch supports Apple Pay, too, although we're still waiting for that to come to the UK. A new Apple Watch app in iOS 8.2 (available to download today) lets you see and download apps. Apple also confirmed there would be all-day battery life of around 18 hours.
