Great app but very buggy – Tone - Learn Perfect Pitch! Review

I like the concept of this app, it allows easy practice and development of musical recognition. But the app can not help if the user is unable to access the majority of it. Every time I click on a Practice button, the app freezes for a moment and then shuts down, no matter the type of recognition. The app also behaves this way when I go to click the left tab.
