Penny-Sized Fitness Trackers

The idea of monitoring one's fitness level might be productive and admirable, but often times it is also inconvenient and frustrating; Goccia by G-Wearables, a team based in San Francisco, California, hopes to change that. It is the world smallest and simplest fitness tracker that ensures people can't use any more of these common excuses.

Shaped like a small button no bigger than a penny, Goccia by G-Wearables uses light to sync with smartphones. Instead of using the typical Bluetooth mode, all a user needs to do is place it face down on their smartphone screen. From there it emits a beam of light that is encoded with all of the obtained data. This data is then displayed on an accompanying app so that people can see how they are improving.
