Nike+ Move

While all your strongest instincts tell you to pack on a few pounds, put on your warmest pair of sweat pants, and just wait the winter out, you can still defy those urges and remain active with Nike+ Move ($Free). Designed exclusively for the iPhone 5s, this app takes advantage of the new M7 motion coprocessor to track detailed information about every type of movement you engage in, throughout the day — all without the need for additional hardware. It charts your movement and gives you points called NikeFuel, letting you compete with groups of friends to see who's the most active. Detailed graphs and charts tell you your most active days, locations where you moved most, and your peak times for movement, even breaking it down by type of movement.
