The Sweatcoin app counts users’ steps through their smartphone and then rewards them with its own cryptocurrency: the Sweatcoin. As of January 18, 2018, it is currently No. 5 out of the App Store’s free apps, only behind the new Google Arts & Culture app, Netflix, Instagram and YouTube.
Sweatcoin has 2 million active weekly users and gained more than five million users overall in 2017. Those who download Sweatcoin can link up their phones’ accelerometers and GPS data to the app. They are then rewarded 0.95 in Sweatcoin for every 1,000 steps they walk. Sweatcoin can be accumulated and then spent within its economy on workout clothing, classes, gift cards, and even iPhones and Apple Watches. Participants can also donate their coin to partner charities.
