Songs are copied into this app. Keep your originals in Files.
Only while practicing in the foreground.
App caching and song storage are checked separately.
Device & storage notes
Music already playing can continue when you switch apps or lock the screen. System play/pause controls are supported where available. Calls or other audio can interrupt playback; it will not resume automatically. Background repeat gaps need testing on your iPhone.
Clearing website data, storage eviction, or changing the site address can make your library unavailable. Reimport originals from Files; offline app setup may be needed again.
The speed range of 75–125% and default gap of 0.5 s are provisional for this first build.
Built-in browser pitch preservation still needs listening tests on your iPhone.
