Useful – Ultimate Music Theory Review

As an adult returning to piano lessons, I am finding this app to be a useful way to review and learn keyboard notes and music theory concepts. It bases the amount of repetition on how you rate your knowledge, so you only "drill" the items you don't already know, or that you are somewhat unsure of. You can track your improvement, too. The app makes good use of color as well as audio & covers a wide variety of music concepts. I have the app on my iPhone & can use it to practice at various times throughout the day. Five stars.
