My immediate thought was SweatCoin, and looking at the comments, I see you see them as a competitor. Having used SC for what seems like years, you need something else to be different from them.
I suggest you hook this on to the blockchain. SC having been promising their token will have some substance for ever, have failed to deliver. Don't be the same as them, as they were here before you.
We hope we're going to be a lot different than SW. In rewards, brand and user-friendliness.
Thanks for the advice!
