BodyMedia introduced the fashion-forward Core 2 fitness tracker, which is a small device that syncs with an iPhone. The waterproof Core 2 keeps track of steps, calories, and length of physical activity. The wearable device has a bracelet-like sleek sliver design. It's the most minimal tracker we've seen, and it stands out among the plastic- and rubber-centric fitness band market.
Body Media also plans to make updates to its Android app, and is working on a disposable stick-on tracker.
