Capture mid-flow without stopping
Hand-gesture save (Pro): raise an open palm into frame and the last 45 s–12 min commits to disk. No walking back to the tripod, no lost concentration. Works at any distance the camera can resolve a hand.
Use case · Updated
ReplayR for dancers and musicians
TL;DR. Solo practice loops are unforgiving — you can't be the performer and the camera operator at once. ReplayR keeps a rolling buffer of the last 45 s–12 min running silently. Nail a phrase or land a combination? Raise an open palm (Pro hand-gesture save) or tap your Wear OS watch — the moment is captured without breaking flow. End the session, swipe through, keep the takes worth keeping. No cloud, no account, no edit timeline.
Why solo practitioners pick ReplayR
Endless rehearsal, fixed disk usage
Rotate 5-second chunks; only the last buffer length lives on disk. A 3-hour rehearsal uses no more storage than 3 minutes. Saved takes export to your gallery only when you explicitly keep them.
Mirror-mode review
Swipe-to-keep at session end with full-screen playback. Trim and slow down (free) to inspect a turn, a passage, or a transition frame by frame in the in-app editor.
Studio-private
No cloud upload, no account, no analytics SDK. The footage stays on your phone — useful when you're filming early sketches you don't want sitting on someone's server.
Setup for dancers
- Buffer: 90 s (free) for short combinations; 3 min (Pro) for full variations or contemporary phrases.
- Mount: tripod at hip height across the studio, full-body framing in landscape.
- Save trigger: open-palm gesture facing the camera at the end of the phrase. Sensitivity step 3 for typical studio lighting.
- Stealth mode on: pure-black screen avoids reflection in the studio mirror.
- End of session: swipe-to-keep, slow the keeper to 0.5×, screenshot the moment a foot rolls or a hip shifts.
Setup for instrumentalists and vocalists
- Buffer: 3 or 6 min (Pro) — long enough for an étude or a take of a song.
- Mount: within 1–2 m of the instrument, lens facing hands and posture, mic side toward the source.
- Save trigger: Wear OS watch tap (silent, no fret-board interruption) or open-palm gesture between takes.
- Resolution: 1080p for posture and finger work; bump to 4K (Pro) only if you'll zoom into the footage later.
- Audio caveat: ReplayR uses the camera mic unmodified — for serious recording, run a parallel multitrack and sync video later.
Why video review matters
Self-modeled video review is a documented motor-learning aid: see the systematic review by Murr et al., Sports Medicine — Open, 2018. The barrier in dance and music isn't the value of replay — it's the friction of capturing only the moments you'd actually re-watch. Rolling buffer removes that friction.
FAQ
Can I save without walking back to the phone?
Yes — Pro adds open-palm hand-gesture save (5 sensitivity steps), or pair a Wear OS watch and tap the Tile.
How long can I rehearse before storage fills up?
The buffer holds only the last 45 s–12 min on disk no matter how long you've been recording. Only the clips you keep count toward storage.
Will the audio capture my instrument cleanly?
Camera-mic quality. For serious music capture, place the phone within 1–2 m, run a parallel multitrack if needed, and sync later.
Does it loop with a metronome or click?
No — ReplayR is a capture tool, not a practice loop tool. Run your metronome on a separate device or app.
