When you subscribe to happn, the app specifies that you will get “up to 10 SuperCrushs per day”. Which means you will get 5 SuperCrushs every 12 hours; however, these SuperCrushs do not add up.
The screen will never display more than 5 SuperCrushs. If you haven’t used all of your 5 SuperCrushs during the first 12 hours, your remaining SuperCrushs will be lost.
