I really like it!
This is a great app for any musician. It is difficult to find enough hours in the day for ear training, practice, and time to listen to recordings. This app gives me the chance to capture some ear training time while on the go. I use it on my lunch hour. I have not had an ounce of trouble with its speed, sound, etc. I like that you can individualize the settings. One can work on major scales/chords or the entire range of scales/chords including minor/modes/etc. I wish I had had this app in college. Theory is a necessary evil in my mind and I am very glad I have this to help me out!
