This is a very well designed app, and it is hard to see how anyone interested in learning music will regret spending $1. Ive used it in the last weeks to learn more about scales, and it is a perfect match with atheory book, as you can hear the scales, practice and ge more information.
A few suggestions for an update: either remove the ovation when the score is high, or allow users to remove it, gets boring and distracting after a while. Also for the ear training section, what about repeating the scale when the answer was wrong and then playing the right one? Even a graphic sample of both wrong/right answers would be very helpful. It would also be great to have samples of music where the different scales are used. Maybe a link to a website with more in-depht info?
Great work!
