Today both Misfit and Speedo have announced a partnership that has produced an all new activity tracker: the Speedo Shine. I suppose we all should've seen that name coming.
The Speedo Shine shares a bit with its cousins like the Misfit Shine, but it's been specifically designed for swimmers - and is waterproof up to 50 meters. So basically it's meant to track laps and is said to support "all stroke types." The device, of course, also syncs with the Misfit app to display burned calories, swim distances, and lap counts. Once the official Speedo swim tracking app comes out you can use it with that, too. It's not just about swimming though, as you can also use it to track cycling, running, walking, and sleeping.
