TL;DR. DecideCam is a cricket-first review camera: a smart buffer that loops 1 to 5 minutes, playback at 0.5× and 2×, frame-by-frame stepping, and framing built around no-balls, wides, edges, and boundary calls. ReplayR is a general sideline capture app with a longer buffer (up to 12 minutes), a Wear OS save, an open-palm gesture, and a review-and-trim pass. Two honest notes: DecideCam gives a longer free buffer than ReplayR free, and it has frame-by-frame stepping that ReplayR does not have. Its last release was October 2025.

DecideCam figures from its Google Play listing (package ai.record.replay, developer 3GRT Interactive, version 1.0 build 104, updated 29 October 2025). Last verified 2026-07-28.
DecideCam frames everything around match officiating in turf cricket: check a no-ball, settle a wide, look again at an edge, confirm a four or a six frame by frame. The 1 to 5 minute loop and the frame-by-frame control both serve that job well, and the app keeps footage on the device.
ReplayR frames everything around a training or match session: buffer runs for hours, you save the moments worth keeping, then you triage and trim them at the end. The two overlap on mechanism and diverge on what happens after the save.
Free buffer length. DecideCam loops 1 to 5 minutes at no cost. ReplayR free is 45 or 90 seconds, and the 3, 6, and 12 minute options sit behind the one-time Pro unlock. If a long free buffer is the only requirement, that is a fair point in its favour.
Frame-by-frame stepping. ReplayR slows playback to 0.25× and lets you trim, but it does not step single frames. That is deliberate, ReplayR is the capture half and exports standard MP4 files for analysis apps. For an lbw shout or a foot-fault call, single frames matter and DecideCam has them.
Reach. The Wear OS companion means the phone can live on a fence post at the boundary while you save from behind the stumps. The open-palm gesture covers solo net sessions. DecideCam expects the phone within arm's reach.
Quality and length. 720p or 1080p is fine for a call; it is thin for technique work on a big screen. ReplayR Pro records at your device maximum, up to 8K, and buffers up to 12 minutes, which covers a full over plus the setup.
Upkeep. DecideCam has shipped one version, dated October 2025. ReplayR is in active development. On a category where Android camera APIs and OEM behaviour shift every release, that matters more than any single feature.
A free Android replay and review camera aimed at turf cricket, published by 3GRT Interactive. It records 1 to 5 minute loops into a smart buffer, plays back at 0.5×, 1×, or 2×, supports frame-by-frame stepping and auto-bookmarking, and keeps all footage on the device. Its listed version is 1.0, last updated 29 October 2025.
No. ReplayR plays back down to 0.25× and has a trim editor, but it does not step single frames. Saved clips are standard MP4 files, so the intended route is to capture in ReplayR and step frames in a dedicated analysis app such as OnForm or Kinovea.
DecideCam has the longer free buffer at up to 5 minutes, against 45 or 90 seconds for ReplayR free. ReplayR Pro goes to 12 minutes, which is the longest in the category, for a one-time $5.49 unlock.
For reviewing calls, yes. For coaching, the limits show up quickly: 1080p maximum, no watch save, no gesture, no trim editor, and no session triage. ReplayR covers run-up, delivery, and shot in 45 seconds free, or a full over on a 3 minute Pro buffer.
One-time Pro unlock if you want longer buffers, hand-gesture save, and 8K capture. No subscription.
