There are many decent activity trackers on the market already. Goccia happens to be another one you can use to track your movement. It is waterproof and as small as a shirt button. Goccia can be worn 24/7. It syncs with LED light communication. It not only counts your steps but burned calories.
Goccia works for various activities, including swimming, hiking, and biking. It even tracks your sleep quality. The device lets you track your progress with a single tap. It is compatible with iOS devices. To sync it with your phone, just place Goccia in front of its camera, and the job is done with a quick tap. The battery will last for 14 days (wireless charging is available). Yet another interesting smart activity tracker.
