Jawbone UP2
A stylish band that can be disguised as a bracelet if you pair with other bracelets. The wrist band offers automatic sleep tracking and the app has smart coaching to help you through your progress. The UP app is the best all-around fitness software available, and we suggest getting the newer version with the flat, lightweight straps (the first generation falls off easily). They come in a few different colors, but we love the all black look. Battery power lasts up to 10 days and only takes one hour to charge fully.
