Once upon a time Jawbone was a company who was mostly invested in making Bluetooth headsets for mobile devices. Since the rise of wearables though, Jawbone like many companies have spent time developing activity trackers, and one of Jawbone's last generation trackers called the UP2 is currently available on sale. Normally the UP2 goes for $99, but you can currently find it on Amazon for $58.31 which is nearly half off, and on top of that Amazon is boasting "frustration-free packaging" when it comes through to your door.
The Jawbone UP2 Activity + Sleep Tracker is capable of quite a few things, like tracking your caloric burn and steps taken as well as your overall exercise. The UP2 keeps users motivated with the help of the Smart Coach to guide you through what to do to stay fit and meet your goals, and when the day is done you can use the UP2 to track your sleep and feed you the data through the companion app so you can see how well you're actually sleeping. In addition to tracking quality of sleep, it tracks how long you slept as well, and you can use the app and tracker together to set and log food habits and goals. The tracker is also splashproof and sweat resistant.
