Good idea but crashes – EarAgeChecker - Your ears right? Review

This app seems very interesting but sadly it crashes very very often, even running the app without touching anything will make itself crash. Another thing would be interesting to see is if the app could just go through a range of testing and actually guess your age instead of filling out a profile and inputting your age at the beginning of the app, some More polishing of the user interface would be great.
