Skill-length buffer, not session-length
A vault is 5–8 s, a beam mount + dismount sequence 15 s, a tumbling pass 4–6 s. The 45 s rolling buffer keeps the whole skill in memory without saving the 2-hour training session.
Use case · Updated
ReplayR for gymnastics coaches
TL;DR. A vault is 5–8 seconds from runway to landing. A tumbling pass is 4–6. A bar release is 1 second. The 45-second free buffer catches the entire skill plus the run-up. Mount the phone, tap save between turns, walk it to the gymnast, they see the rep before the next one starts. On-device only: no cloud upload, no minor's footage leaving the gym.
Why gymnastics coaches pick ReplayR
Routine mode for optionals
Switch to the 90 s buffer (or Pro 3 min) for full beam, floor, or bars routines. Save once at the end and the entire routine is on the phone before the next gymnast salutes.
Athlete-side review in seconds
Save → walk → show. No tablet, no SD card, no "I'll send it later." The coaching cue lands while the kinaesthetic memory is still warm.
No cloud, no minor footage online
Footage stays on the device. Critical for under-18 athletes, GDPR-conscious clubs, and parents who don't want their kid's training videos in a third-party bucket.

A typical training session
- Set tripod once per apparatus rotation.
- App opens, recording starts, screen sleeps, battery survives a 3-hour session with a power bank.
- Gymnast goes. You watch live, not through a screen.
- Tap watch on land. 45 s saved.
- Walk over, show the gymnast the rep, give one cue.
- Next gymnast goes. Repeat.
- End of session: 30 saved skills in a folder, not a 2-hour MP4.
FAQ
What buffer length works best for gymnastics?
45 s covers any single skill. Use 90 s buffer for full routines (beam ~70–90 s, floor 60–90 s). Pro 3 min handles championship-level routines with overrun.
Can I review with the gymnast immediately?
Yes, that's the point. Save → walk → show. The feedback loop closes before the next attempt.
Will it pick up the buzzer or commands?
Audio records by default, useful for the 'go' command and landing thump. Disable in settings for noisy gyms.
Is footage safe for under-18 athletes?
Yes, ReplayR is on-device only. Nothing uploads. Coach controls who the phone is shown to and when clips are deleted.
