Unlike most other trackers, Misfit Shine is powered by a watch battery, so there’s no need to charge it. This tracker allows users to monitor steps, fitness activities and sleep, set daily goals, and keep a photo food journal. Plus, it can be worn as a necklace or bracelet if you slip it into a compatible design, like the Swarovski collection, which is perfect if you want to wear something that's not so obviously a fitness tracker. Also, Speedo Shine is ideally designed with swimmers in mind. Made out of durable aircraft-grade aluminum, this nifty device is waterproof up to 50 meters and has special swim tracking capabilities, such as monitoring a swimmer’s lap count and swim distance and works for all stroke types.
