Frequently asked questions
How do I move to another score?
Tap the score or swipe left. When piano listening is enabled, playing the displayed notes can advance the score automatically.
Why is microphone access requested?
Microphone access is optional and is used only for on-device piano listening. Note Crush does not record, save, or upload microphone audio.
How do I enable microphone access?
Open Settings on your iPhone or iPad, find Note Crush, and enable Microphone. You can continue using manual practice without microphone access.
Can I change the notes used for practice?
Yes. Open Filter to choose pitch ranges and key signatures. Treble and bass clefs can use independent settings.
Which devices are supported?
Note Crush supports compatible iPhone and iPad devices running iOS or iPadOS 17 or later.
