Sweet App. Only a couple problems, Sometimes I set a new record and am not given the option of saving it.....only continue, hint, or reset., Very frustrating little bug, perhaps the option to save score at every mistake would be viable? Also sometimes when I get stuck at a section I've already memorized, I am given the option of "hint", or "continue", but no "reset", and at that point I have to close the program and reopen it, because what I want to do is start over.
