Nice app, but needs more challenging tests

This is a very nice and useful app. The ear training exercises are however somewhat basic (interval recognition within a single octave), and any good musician will quickly reach the highest difficulty level. Hopefully future updates will correct this deficiency. We need more intervals (9ths, 11ths, 13ths), and CHORDS!!! (major, minor, with and without 7ths, dominant, altered dominant chords, diminished, augmented, sus4, etc...)
