Like the Fitbit, the Misfit Wearables line of devices lets you track your physical activity throughout the day. It transmits that data to your iPhone via a forthcoming app that provides an overview of your activity. The basic Shine tracker is US$99; accessories to clip it to your body during the day range from US$5 to US$49. The Shine is expected to ship in July.
US$99 + shipping
