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.

A real session with ReplayR

Sofia coaches junior tennis players. She used to record full 90-minute sessions and spend 20 minutes scrubbing for useful clips. Here's what her Tuesday practice session looks like now.

3:30 PM · Setting up courtside

Sofia props her phone against her ball cart with a small tripod wedge, aimed at the baseline. She opens ReplayR, taps Start buffer. The rolling window is set to 90 seconds, enough to cover a full rally exchange. The screen goes dark (stealth mode). The buffer is running.

3:47 PM · A rally worth keeping

One of her players has a backhand that breaks down under pressure. The drill just produced a perfect example, the exact moment the elbow drops. Sofia glances at her Wear OS watch and taps Save. The last 90 seconds are written to local storage. The buffer keeps running. Play continues without interruption.

5:00 PM · End of session review

She saved 8 clips across two hours. ReplayR shows them in the swipe-to-keep queue: swipe right on the good ones, left to discard. She keeps 5, trims two in the built-in editor to show just the stroke, and shares them via Quick Share. No login. No upload queue. Two minutes total.

Zero dead footage on the device

The 90-second buffer never fills her storage. Only the clips she explicitly kept were written to disk. The two hours of practice that produced nothing worth saving? It was never stored. Her phone has the same free space it started with, minus five clips.

What ReplayR doesn't do

ReplayR is a capture tool. It's deliberately not a full analysis platform, understanding the edges helps you decide if it fits your workflow.

No automatic cloud backup

Clips stay on your device until you share or export them. There's no background upload to a cloud library. This is intentional, it means no accounts, no tracking, no clips leaving your device without your say-so.

No drawing tools or frame-by-frame annotation

ReplayR has a trim editor and slow-motion playback, but it doesn't let you draw arrows on clips or add telestrator annotations. For deep frame-by-frame breakdown with drawing tools, pair it with a dedicated analysis app after capturing the moment.

Not a full-session recorder

If you need a complete, uninterrupted recording of an event, every minute, every moment, ReplayR isn't it. The rolling buffer discards footage that wasn't explicitly saved. For archival full-session recording, use your phone's native camera app.

No iOS support yet

ReplayR is Android-first today, with a full Wear OS companion. iOS support is on the roadmap but not yet available. If you and your athletes are split across platforms, Android is the side that works today.

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.
