Includes a 'Grade Book' list of all saved quiz results that you can edit and create a pdf of to print or email.

• Set separate maximum number of sharps or flats for the quiz.
• Set only major and minor keys, only the seven diatonic modes, or combine both groups into the quiz.

• Treble, Alto, Tenor, and Bass clefs.

• Optionally record how long it takes to finish the quiz.

The Grade Book is filterable by student name. Access to the list can be password protected by entering a password in the device's Settings app.

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.
