Music Wall needs permission to read your Apple Music library. Open Settings › Privacy & Security › Media & Apple Music and turn on Music Wall. If Screen Time is on, check Settings › Screen Time › Content & Privacy Restrictions as well.

Make sure your library has albums or playlists in the Music app, and that you are signed in to the same Apple Account. You can reload it with Refresh Library in Music Wall’s Settings › Library.

• Check that your Apple Music subscription is active in the Music app.
• Some songs aren’t available in every country or have been removed from Apple Music.
• If the Music app asks you to accept new terms, open it once and accept them.
• Check your internet connection, then try again.

Lyrics come from LRCLIB, a community lyrics database, and not every song has them yet. Lyrics can be turned on or off in Settings › Player › Show lyrics.

Every feature is free for 24 hours, starting when you tap the button on the last welcome page. During the trial you can buy Music Wall at a lower trial price.

After the trial you can still browse your wall; everything else needs a one-time purchase. It is not a subscription and never renews.

iPhone and iPad share one trial. A Mac has its own. Deleting and reinstalling the app does not start a new trial.

Sign in with the same Apple Account and open Music Wall; it unlocks automatically. If it doesn’t, tap Restore Purchase on the purchase page or in Settings. One purchase covers iPhone, iPad and Mac.

Yes. Music Wall supports Family Sharing. Family members open the app with their own Apple Account, and it unlocks once Family Sharing is on for purchases.
