THE PROBLEM IS... – Mathdoku+ Sudoku Style Math & Logic Puzzle Game Review

I love the puzzles but I HATE that the app doesn’t save my puzzle if I close out of the app or the app crashes (which it does). Sometimes the puzzles take an hour to complete and I’d like to be able to work on it at different times throughout the day. Fix that and you get 5 stars. I took away 2 stars for that sole reason.
