Ive been playing with this app for a while now. I have several things to say:
This application has a LOT of potential for developing your Chord Ear. The person who created this knows how to train someones ear, and probably has a very advanced ear himself to begin with.
I know its the first version ever to be launched, but for this app to deliver its full potential, I feel it must have more scales (probably training on all the modes), there should be levels where you combine Triads with 7ths as to help in real life situations. The app is really fun, and that it why it is so effective, I cant imagine having all the options I listed above available. It would make this great app, into an amazing app. And probably the best ever to be created
