TL;DR. These are the two honest answers to "video delay app", and they work differently. BaM Video Delay shows a continuous live feed on a fixed lag, configurable from 1 second to 6 minutes: every rep replays automatically, nothing is kept. ReplayR runs a rolling buffer and keeps only what you save (45 seconds free, up to 12 minutes Pro) via phone, Wear OS watch, or open-palm gesture, as MP4 clips ready for slow motion and sharing. Delayed mirror vs replay-on-demand; pick by whether anyone can trigger a save.
| Feature | ReplayR | BaM Video Delay |
|---|---|---|
| Model | Rolling buffer + triggered save | Continuous delayed feed |
| Every rep replays automatically | No, only saved reps | Yes, on the fixed lag |
| Keeps clips as MP4 on device | Yes, save writes last N seconds | Delay-first; keeps nothing by default |
| Hands-free trigger (watch, palm gesture) | Yes, Wear OS + open-palm (Pro) | Not needed; nothing to trigger |
| Delay / buffer range | 45 s free, 90 s–12 min Pro | 1 s–6 min lag |
| Slow-motion review of kept clips | Yes, 0.5× / 0.25× + trim | Slow motion and pause on the feed |
| Multiple simultaneous views | No | Up to 4 views |
| Works offline, no account | Yes, on-device only | Yes, no login |
| Platforms | Android + Wear OS (iOS WIP) | iOS + Android |

The models are complementary, and plenty of gyms run both. Put a spare phone or tablet on a tripod as the continuous delayed mirror at the self-serve station: every athlete sees their rep on a 10 to 20 second lag, no interaction needed. Keep ReplayR on the coach's phone with the watch trigger for the moments worth keeping: the breakthrough attempt, the recurring fault, the PR. Full setup recipes are in our video delay apps for coaching guide.
BaM Video Delay shows a continuous live feed on a fixed lag of 1 second to 6 minutes: every rep replays automatically and nothing is kept. ReplayR runs a rolling buffer and keeps only the attempts you save by phone tap, Wear OS watch, or open-palm gesture, as standard MP4 clips with slow motion. One is a delayed mirror, the other is replay-on-demand.
A continuous delay app like BaM. If nobody can trigger a save, not even hands-free, a fixed-lag feed that replays every rep automatically is the right model. ReplayR is better as soon as someone can trigger: you end the session with a folder of the reps that mattered instead of nothing.
BaM is delay-first: its job is showing the feed on a lag, with export options for moments you act on. ReplayR is save-first: every triggered save writes the last N seconds to a standard MP4 on the device, ready to trim, slow down, and share. If the session's output should be a set of clips, that is ReplayR's home ground.
Not on one phone, both need the camera. Coaches who want both models run two devices: an old phone or tablet as the continuous delayed mirror at a self-serve station, and ReplayR on the main phone with the Wear OS watch for triggered saves of the attempts worth keeping.
