I have loved every part of this app. I used it with my high school students last year and will continue to do so. The only thing I would change is have some way that students could send feedback back, including how many they got correct.
Really excellent to train the ear.
Innovative idea I can tell that I am improving already because of the graphing feature! I highly recommend this app to anyone who is interested in ear training.
