About
Start a tune in a minute. Let the world finish it.
Tap notes on a grid, pick an instrument and hear your melody right away. No mic, no recording, no music theory.
Publish it, and anyone (or only your friends) can continue your song.
HOW IT WORKS
• Make a short tune: tap notes, choose instruments, add a drum part.
• Publish it to the feed, or send a link to a friend.
• Others continue it: each continuation is a new version you can play and follow.
• Everyone gets credit: the idea's starter and every contributor are named on every version.
WHY YOU'LL LIKE IT
• Made for people who love music, not just people who make it.
• Browse the feed and play songs before you sign in.
• Choose who can continue your song: anyone, friends only, or closed.
• Get a notification when someone continues your song.
• Songs play on your device, so they open fast and use little data.
COMPOSE ON PREMIUM (optional)
Compose On is free with ads, and you can start a limited number of songs. Continuing songs is always free and unlimited. Premium removes ads, raises the limit on songs you start, unlocks the full instrument library and lets you save a song as an audio file. Monthly and yearly plans are auto-renewing subscriptions charged to your Apple Account. The yearly plan may include a free trial. The price is shown before you subscribe. Subscriptions renew unless cancelled at least 24 hours before the period ends; manage or cancel them in your Apple Account settings.
COMMUNITY
Compose On is for people 18 and over. Songs, names and comments are created by users and are screened automatically. You can report or block anyone in the app, and we review reports within 24 hours.
