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.
Apparatus setup
Vault
- Mount: tripod at the end of the landing mat, level with the vault table, lens at hip height.
- Buffer: 45 s — covers run-up to landing easily.
- Resolution: 1080p for block angle and body shape review.
- Save: watch tap as the gymnast salutes after landing.
Beam
- Mount: 3–4 m back from one end, lens at beam height.
- Buffer: 45 s for skills · 90 s for full routine.
- Resolution: 1080p for series and leap split angles.
- Save: watch tap on dismount stick.
Bars (UB / HB)
- Mount: side-on, capturing both bars in frame, far enough to fit release skills.
- Buffer: 45 s for releases · 90 s for full routine.
- Resolution: 1080p — useful for hand placement and giant tap timing.
- Save: watch tap on dismount.
Floor / tumbling
- Mount: behind the corner, low angle to capture rotation and height.
- Buffer: 45 s for passes · 90 s for full floor exercise.
- Resolution: 1080p for twist count and landing leg shape.
- Save: watch tap after stick.
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.
