UP fitness wristband

Who makes it: Jawbone
What it costs: $100
Why we like it: This colorful, deceptively simple waterproof wristband houses a motion sensor that measures your steps and sleep patterns. The band can also be set to remind you to move around if you've been sitting for too long. A free iPhone app keeps track of it all and connects you with friends for mutual support and encouragement.
