TL;DR. Both keep a rolling buffer so you can save what already happened. The split is scope. Flashback is a general-purpose pre-roll camera with a 30 second ceiling and a subscription, strongest on the free tier where it records 1080p. ReplayR is built for sessions: 45 seconds free, up to 12 minutes with a one-time Pro unlock, plus a Wear OS watch save, an open-palm gesture, and a swipe review pass at the end. If you film sport for more than a few minutes at a time, buffer length and the save trigger decide this one.

Flashback figures from its Google Play listing (package com.rochapps.flashbackcam, version 1.0.34, updated 19 April 2026). Last verified 2026-07-28.
Flashback buffers between 3 and 30 seconds, and the free tier gives you 10. That is sized for a skate trick, a dog doing something stupid, or a near miss caught on a dash mount. It is genuinely good at that.
Sport breaks the ceiling fast. A tennis rally runs 20 to 45 seconds. A hockey shift is 40 to 60 seconds plus both changes. A rugby phase that leads to a try started three phases earlier. By the time you have watched the moment, reacted, and reached the phone, a 30 second buffer has already eaten the start of it. That is why ReplayR free starts at 45 seconds and Pro goes to 12 minutes: the buffer has to be longer than the thing you are trying to keep, plus your reaction time.
Flashback wins on resolution. Its free tier records 1080p at 30 fps, while ReplayR free caps at 480p and puts 720p through 8K behind the Pro unlock. If image quality on a zero-cost tier is the deciding factor, Flashback free looks better on paper.
ReplayR free trades pixels for reach and workflow. You get the full 45 or 90 second buffer, the complete Wear OS companion including the Tile and Complication, stealth mode, the swipe review pass, and the trim editor, with no ads. For coaching, 480p of the right five seconds beats 1080p of the wrong ten.
Flashback expects your hand on the phone. There is no watch app and no gesture trigger, so the phone has to be reachable, which means it sits close to you rather than where the shot is best.
ReplayR is built for a phone on a tripod at the far end of the court. Save with a tap on a Wear OS watch, from the watch face itself through the Tile or Complication, or by holding an open palm to the camera when you are the one training and there is no one behind the lens. That is the difference between filming yourself and asking someone else to press a button for you.
There is a free tier: 1080p at 30 fps with a 10 second buffer, with ads. The premium tiers (monthly, yearly, or lifetime) unlock 4K at 60 fps, the full 30 second buffer, and remove ads. ReplayR is free with a one-time $5.49 Pro unlock and no ads on either tier.
ReplayR, by a wide margin. Flashback tops out at 30 seconds. ReplayR gives 45 or 90 seconds on the free tier and 3, 6, or 12 minutes with Pro, which is what full-length rallies, shifts, rounds, and routines need.
No. As of July 2026 there is no Wear OS companion and no gesture trigger, so saving means reaching the phone. ReplayR ships a full Wear OS app with a Tile and a Complication, plus an open-palm gesture on Pro.
ReplayR, for buffer length and the hands-free save. Flashback is the better pick if your clips are short, you want free 1080p, and you keep the phone in your hand.
One-time Pro unlock if you want longer buffers, hand-gesture save, and 8K capture. No subscription.
