"Better Ear" is an ear training app, its designed to be fast and practical without the need to navigate menus and configurations to change the jump or the chords which youre intended to train.
It comes equipped with two different interfaces: portrait mode to focus only on notes with a wider extension, and landscape mode to relate notes and their harmonic function.
We strongly suggest you practice singing the notes youre listening to, thats the best way to effectively improve your ear!
