Gameplay
Locked to the music.
Notes race down five lanes in time with the song, from the first bar to the last.
Music videos
When a song has a video, it plays behind the highway, perfectly in time.
Lyrics
Sing along. The words light up as the song plays.
Streaks
Keep the streak going and the multiplier climbs to 4x, and to 8x with star power.
Library
Your music, ready to play.
Bring the song folders you already have. Pick one, choose your instrument and difficulty, and play.
Mac
On your Mac, too.
Play on the keyboard, with the whole library in one window. Write a chart for any song by playing along, slowed down.
Details
Thought through.
Import
Add song folders from Files, iCloud Drive or a drive. A .chart or .mid file and its audio is all a song needs.
Every chart
Every difficulty, tempo change, section and solo, played as written.
Artwork
No video? The background takes its colours from the album art.
Calibration
Calibrate once on iPhone and every song is timed to your setup.
Leaderboards
Every song has its own board, and only runs that were actually played count.
Apple TV
Coming soon: the game on your TV, with your iPhone as the controller.
Free on iPhone and Mac.
Bring your own songs. No music is included.
Requires iOS 26 or macOS 26. Sign it yourself with AltStore, SideStore or Sideloadly on iPhone, or Control-click and Open on Mac. How to install
