Looking for the best sign up bonuses you can cash out? Here are 4 of the best sign up bonus apps we recommend! Check out our full article for all 6 App recommendations!
1. Opinion Inn is our top pick because of their $10 sign-up bonus, which is the highest out there right now. This is also a true sign-up bonus, meaning they pay you just for signing up.
While you need 2,500 SB (or $125) within your first 60 days to unlock the sign-up bonus, based on this guide, you could hit $125 just by downloading and playing Mafia City for 10 hours.
