Perfect and simple app. The problem is that the progress isn't saved when I close the app, so I have to start from the first exercise to get to the sharps and flats, which is simply frustrating and a loss of time. And on the other hand there should be an option for getting completely random notes on a given chosen range, not in any particular key or level. Uninstalling for now, hopefully the saving system is added. I don't understand the difference between the practice mode and the "game" mode
