How it works
Pick the juz you want to revise, in your own order, and say how much time you have. It plans every day until Ramadan. A rusty juz is rebuilt a quarter at a time, then joined: recited whole from memory with the mistakes counted. Ready juz come back for spaced reviews. Miss a day and it simply plans again.
