ReplayR FAQ
TL;DR. ReplayR is a sideline replay camera with a continuous rolling buffer (45 s–12 min). On-device only — no cloud, no account, no tracking. Pro is a one-time unlock at $14.99 (launch price $9.99) for longer buffers, 8K capture, hand-gesture save, and bin restore. Wear OS Tile + Complication ship in the free tier.
How does the rolling buffer work?
ReplayR records the camera into 5-second chunks on disk. Chunk count = buffer duration ÷ 5 s — a 90-second buffer holds 18 chunks. As new chunks arrive, the oldest is overwritten. Save concatenates the buffered chunks via FFmpeg with no re-encoding (~200–500 ms).
How much storage does it use?
Buffer holds only the last buffer length on disk. At 480p, a 90 s buffer is ~60–80 MB. At 1080p (Pro), ~200–300 MB. Saved clips at 1080p run ~10 MB per 10 s. Free up 2 GB before long sessions.
Does it drain my battery?
Less than full-session recording. Stealth mode (pitch-black screen) drops display draw for sessions over an hour. Plug in for 90+ min.
Does ReplayR upload my videos?
No. Strictly on-device. No cloud uploads, no accounts, no tracking. Nothing reaches your gallery until you keep a clip.
Is there a Wear OS companion?
Yes — full remote (start, end, save, pause, set clip duration) plus Tile and Complication for one-tap save from any watch face. Free for both tiers.
What about Apple Watch?
A watchOS companion exists in the codebase but the iOS app is not yet publicly shipped. Android + Wear OS is the supported pairing today.
What capture resolutions are supported?
Free: up to 480p. Pro: 720p, 1080p, 1440p, 4K, 8K (capped to your phone's camera).
What output format are clips?
MP4 (H.264). Concatenation is stream-copy, no re-encoding — saves are fast and lossless against the captured source.
How does open-palm hand-gesture save work?
Pro. A BlazePalm TFLite model runs on live camera frames. Raise an open palm into frame and ReplayR saves. Sensitivity tunable across 5 steps.
Is there a subscription?
No. Pro is a one-time non-consumable IAP (replayr_pro). Standard $14.99. Launch $9.99 (first 3 months). Early supporter $7.99 (first 1,000 buyers).
What does Pro unlock?
3 / 6 / 12 min buffers, 60 s / 2 min / 5 min / 10 min clip durations, 720p–8K capture, open-palm hand-gesture save, bin restore.
What languages are supported?
Six: EN, FR, ES, DE, IT, PT-BR. Auto-detects device language.
What happens to clips I toss?
Bin with 24-hour recovery. Pro can restore; on Standard, restore is paywalled, delete still works.
Do I need an account?
No. No sign-in, no email, no profile. Pro entitlement tied to your Google Play account.
Can I trim or slow-mo clips?
Yes — trim and playback speed in the in-app editor, free. For telestration export the MP4 to a dedicated analysis app.
Does it work on iOS?
React Native (Expo SDK 55) — iOS is not shipped publicly yet. Android + Wear OS is the live combination.
How do I report a bug?
