1. Nike+ Fuelband SE
Do you use more energy playing football than your friend does jogging? What about your mum walking to the station every day, or your brother who cycles to work? Or your girlfriend who refuses escalators and takes the stairs at work every time? This is your chance to find out. The Nike+ Fuelband SE may look a little like a charity wristband (it’s actually a fixed shape, so less comfortable to wear than those charity bands), but make no mistake – beneath the slightly rubbery surface, this bangle packs a techie punch. It has an accelerometer that tracks motion, and a button you press when you’re about to start vigorous exercise or go to sleep. It calculates how active you are in Nike’s own units of “Fuel”. Like other fitness bands, it synchs with apps or laptops over Bluetooth so you can track your progress. The Fuelband SE also lets you share your good news (read: gloat) on social media – and see how you measure up against 149 other people in a Nike+ group. Comes in four colours and three sizes, and unlike many wristbands, it actually tells the time. Radical.
