Not to learn new things

This app does a pretty decent job on reviewing what you already know, however, if you’re hoping to learn anything from it this is not the app(s) for you. It doesn’t have lessons or teach you anything about why you were wrong. It’s simply you’re right/wrong, next question. The only other issue I have is with the notes specifically, you have to press piano keys instead of just being able to tap on a letter/accidental. For those who do not yet know how to translate sheet music to piano specifically that may be a little extra challenging.
