Pick an instrument (piano, guitar or drums), a song and a difficulty, then tap Play. On iPhone Duo, half-fold the phone like a tiny laptop: the top screen shows the notes and the bottom screen is your instrument. On other iPhones the screen splits into a top highway and a bottom instrument.

Open Settings (the gear icon) and run Audio calibration, especially if you play with Bluetooth headphones, which add a delay. You can also change the note speed there.

Play in your room needs camera access and a reasonably well-lit, flat surface. Allow the camera in Settings › Privacy & Security › Camera › Band Duo, move the phone slowly so it can find the table, or use the “Place it here” option. You can also turn the room view off and play in the virtual room.

They use Apple's Game Center. Sign in under Settings › Game Center on your iPhone, then reopen Band Duo. Band mode is for up to 3 players and Versus for up to 4, and everyone needs Band Duo, Game Center and an internet connection. The game is fully playable without Game Center.

Yes. Single-player songs work without an internet connection. Leaderboards, achievements and multiplayer need a connection.

No. Band Duo is a one-time purchase with no ads, no accounts and no in-app purchases.

Purchases are handled by Apple. To ask for a refund, go to reportaproblem.apple.com, sign in with your Apple Account, find the purchase and choose Request a refund. Apple decides refund requests under its own rules; we can't issue refunds ourselves.

Band Duo keeps your scores and settings only on your device, so deleting the app removes them. Game Center scores are managed by Apple in Settings › Game Center.
