Get it all back
Finish and your money is back within minutes of settling, 3 hours after your last day ends.
Every cent in your wallet
Meet Grin. He walks with you.
Grin is the Grinda lion. He tells you exactly how far to go, cheers when you hit your goal, and his mane grows with every goal day in the last two weeks. Miss a day and it just stops growing for a bit. No guilt trips.
How we make money, in plain words.
From stakes on missed races, and from Grinda Pro. We'd rather you finish, so everything in the app is built to get you over the line. We publish our books live.
