App glitches

The app is built to have two pains in the quiz section. The left side is to choose which quiz you want to take. The right is the actual quiz. However, if you leave the app mid quiz and then come back and select a different quiz, the second quiz opens up in the left pane. From there, you can't shut the two quizzes down to get back to the quiz selection menu on the left. The only work around is to clear the iPad memory and reopen the app, something that is unacceptable.

I really like the easy accessibility of this app. It's simple and has the properties of each AA (polarity, structure, letter codes, etc.) It even tells you if it's an essential AA and includes the codons for it. Overall, it's great for reviewing the AAs and for quick access information on them. !!
