SweatCoin is a step tracking app. You earn SweatCoins which can be used to redeem for fitness gear, electronics, or other cool rewards. The rewards change daily.
1000 steps equal 1 SweatCoin.
They have a battery saver mode but it comes at the cost of not tracking as many steps. I don’t use battery saver mode because I have a portable backup battery I use if my iPhone battery gets too low.
This app also has membership tiers. The more steps you have per day, the higher required membership to convert those steps to SweatCoins.
Another fun thing through this app is In-Voting offers. Other users can post items they want to sell through the app. You can post your own items or services for others to purchase using SweatCoins. When you post an item or service, other users vote on including it in the Available Offers section of the app. Once it gets there, they can purchase it and you earn the SweatCoins!
Available in the US, UK, and they are working on adding other countries.
