Sweatcoin is a free app used by over 200 million people worldwide that converts verified outdoor steps into spendable in-app currency.

Download the free app on iOS or Android and it uses GPS to verify outdoor steps (indoor/treadmill steps do not count), converting them into “Sweatcoins” redeemable for gift cards and gear.

The base tier is free, with a daily earning cap; a paid Boost subscription unlocks higher tiers if you want to earn faster.
