With so many activity trackers on the market, it’s hard to know which device or method to use. Goccia is the world’s smallest and simplest activity tracker, and features more advanced capabilities than its competitors. This device is able to recognize which type of activity you are doing (swimming, playing tennis, walking), and adapts itself accordingly. It tracks all of your activity for you, so you don’t have to waste time entering numbers and keeping time. It also records your steps, calculates calories, times, distances, and measures quality of sleep and other-health related metrics.
