AB Repeater

See what's next. Give yourself room to come in. Practice singing, instruments and dance with early cues and context around each loop.

AB Repeater turns video and audio into practice segments you can loop freely. Instead of resetting A and B every time, choose the segments you've already made. Work on one phrase or movement, then move on when you're ready.

SEE YOUR NEXT CUE EARLY
Add your own lyrics, playing reminders or choreography notes to each segment. Show a note before its segment starts so you can prepare for the next line, phrase or move. Set the lead time from 0 to 3 seconds and adjust transparency. Place video notes wherever you want, like captions; audio notes stay in a fixed position. You write the notes yourself—lyrics and captions are not generated automatically.

PRACTICE THE ENTRY AND THE TRANSITION
Add 0–1.5 seconds of source video or audio before and after each selected loop. Hear or see what leads into the segment and what follows it, instead of practicing only between two abrupt cuts. This is playback context, not an added silent pause. Adjust it separately from how early your cue notes appear.

MORE PRACTICE, LESS PHONE CONTROL
Create segments with beat analysis or a BPM you enter, then select the parts to repeat in order. Slow down a movement, revisit a tricky phrase, or switch your practice focus without rebuilding your loop from scratch. Review and adjust beat-analysis candidates before applying them. Audio with changing BPM is not supported.

KEEP THE DETAILS YOU WANT TO REMEMBER
While editing a note, only that segment loops. Move to the previous or next segment to keep adding notes. Audio notes are also a place to sketch choreography ideas. Export a video with your notes to Photos, or export a project containing the source media, segments, beat-analysis settings and notes to import on another device.
