I loved it, it was a (free) digital art app that has smooth lines and a working soft eraser. HOWEVER, when you're drawing, your auto-recovery will kick at intervals you select, but this creates a giant message in the middle of your screen. If you were to accidentally click this big message, it takes you all the way to the main menu and ask if you want to reopen the recovered file. IF you click no you lose everything between saves, gone forever. Too bad they put an ad wall on saving frequently.
