4B Music Support

How do I add music to the app?

Tap the + button on the Home screen to import audio files from your device. You can also add files through the iOS Files app — any audio files placed in the 4B Music folder will be detected automatically.

What audio formats are supported?

4B Music supports MP3, M4A, WAV, FLAC, OGG, and AAC formats.

Does the app work offline?

Yes. All imported music is stored locally on your device and plays without an internet connection. The app has a dedicated offline mode.

How do I enable background playback?

Background playback works automatically. Start playing music and switch to another app or lock your device — playback will continue. Use the lock screen controls to pause, skip, or adjust volume.

How do I delete my data?

Go to Settings and use the "Clear Data" option to remove all local music and app data from your device.
