why 4 hour of reffil ????

Question

why i want it short atleast 2 hour its pay to win not fair

Answer 1

Well, Sololearn sets the 4-hour refill so learners pace themselves instead of rushing. It’s not really “pay to win” — the heart system is meant to encourage careful learning and practice. If you want faster progress you can use the Pro plan.
But even if you run out of hearts, you can still practice by using the Code Playground in the app. That way you don’t lose learning momentum while waiting for the refill. Good luck!
