Singsong: Karaoke & Practice

Any song you already own becomes karaoke. Singsong uses on-device AI to strip the vocals out of tracks in your own music library — no catalog to subscribe to, nothing to rent, and your music is never uploaded for separation.

THREE WAYS TO SING
One tap apart, so you can learn a song and then own it:
• Singalong — original vocals stay in while you find the melody.
• Guided — the vocals duck under yours, so you lead but never lose your place.
• Karaoke — vocals off. The stage is yours.

MAKE THE SONG FIT YOUR VOICE
Every voice is different, so move the song to you:
• Adjust Key — transpose up or down without changing the tempo.
• Adjust Tempo — slow a fast song down without dropping the pitch.
Nail the hard part at half speed, then bring it back up to tempo.

SYNCED LYRICS, LINE BY LINE
Lyrics scroll in time with the music and highlight the line you're on — full screen when you want nothing but the words in front of you.

FLAG THE HARD PART
Drop a flag on the bar that keeps tripping you up and jump straight back to it with a 10-second lead-in. Rehearse the chorus, not the whole song.

RECORD, REFINE, KEEP YOUR BEST
Record your take over the backing track with live mic monitoring and latency calibration, so your voice lines up with the music instead of drifting behind it. Keep it Dry, Wet, or Mixed, star the runs you're proud of, and export any take as an .m4a to share.

YOUR LIBRARY, YOUR DEVICE
Vocal separation runs on your device — your music is never uploaded. Once a song is set up you can sing it fully offline, and your library syncs across iPhone and iPad with iCloud.

WHAT'S FREE
Every song in your library, all three modes including full Karaoke, unlimited on-device backing-track generation, importing your own instrumentals, auto-fetched synced lyrics, practice flags, key changes up to one semitone, tempo from 90% to 100%, and your first recording.
