Accuracy indicators for rushing and dragging are very useful, but equally interesting would be an indicator that checks for a consistent peaks, so every note is played with equal volume. A dream would be if your app can detect differences in sound (fingernails occasionally scratching the string, fretbuzz).

Is there any way to get notified when your app is done, or do you have a name for it already so we can search for it in a couple weeks?

Love those ideas, would be awesome for really nailing down consistent tones. Latter one would be fairly ambitious for me but I'll keep it in mind for future improvements.

Just published the waitlist[1], the app will be called ShredBlocks.
