ReplayR
ReplayR is your sideline replay camera. Save only the seconds worth keeping.
ReplayR is a sideline replay camera app for Android and Wear OS that keeps a continuous rolling video buffer on your phone. Mount your phone, let it loop, and save the last 45 seconds (up to 12 minutes on Pro) with a tap, your smartwatch, or an open-palm gesture. At the end of the session, swipe right to keep, left to toss, trim in the built-in editor.

What’s inside ReplayR?
FAQ
How does the rolling buffer work?
ReplayR loops over the last 45 or 90 seconds (3, 6, or 12 minutes on Pro). Older footage is overwritten — only the last buffer length is stored until you tap save.
Does ReplayR upload my videos?
No. Recordings stay strictly on-device. No cloud uploads, no accounts, no tracking. Nothing is written to your gallery until you explicitly keep it.
Is there a Wear OS companion?
Yes. Start, end, save, pause, change clip duration — all from your wrist. Includes a Wear OS Tile and Complication for one-tap save from any watch face.
Is there a subscription?
No. Pro is a one-time unlock — longer buffers, longer clips, capture up to 8K, hand-gesture save, and bin restore.
Does it drain my battery?
Less than full-session recording. Stealth mode keeps the screen pitch-black while buffering to save battery on long sessions.
