What instant replay is and how a replay camera app works
Instant replay means saving the video after the play already happened. KplaWY keeps a continuous buffer of the last seconds: when you tap REPLAY, the previous seconds become a clip. You never have to press record beforehand.

What an instant replay app is
On TV, the replay shows the play again seconds after it happened. KplaWY brings that idea to your game: your phone frames the court the whole time, keeping only a recent window of video in memory.
When the point ends, you tap REPLAY and the app cuts the previous seconds into a clip that is ready to watch and share. No hunting for the best moment in hours of footage.
Buffer vs continuous recording
Continuous recording saves everything, from warm-up to the end of the match, eating gigabytes on your phone. The buffer keeps only the last seconds in a loop: anything older than your setting is discarded automatically.
In practice, you leave the match with a few short clips instead of one giant file. Less storage used, less time editing, more plays shared.
| Factor | Continuous recording | KplaWY buffer |
|---|---|---|
| When to press | Before the play | After the play |
| Phone storage | Hours of video | Only saved clips |
| Best moments | You search later | You pick live |
| Battery and focus | Records the whole game | Runs light in the background |
When to use it — and when not to
Use it whenever the phone can sit still framing the action: footvolley, soccer, volleyball, beach tennis, tennis, skate sessions, and technical training. Point-and-rally sports are the best fit.
It is not a security camera or an event recorder: if you need the whole game on file, record normally. KplaWY exists for the seconds that matter.
Remote control: watch, button, or another phone
Your phone can stay on the tripod while you play. Trigger from Apple Watch, Wear OS, a compatible Bluetooth button, or another phone on the local network.
That changes everything mid-game: no running to the tripod, no stopping the rally, no asking someone to film.
Multi-camera and privacy
On the Pro plan, several phones record the same play from different angles and answer the same command. One tap, multiple angles.
Videos stay on your device, with no ads and no advertising tracking. Backup is optional, to your own storage.
Frequently asked questions
What is the difference between instant replay and normal recording?
With normal recording you press REC first and keep everything. With instant replay the camera only keeps the last seconds in a buffer, and you decide to save after the play happens, keeping just the part that matters.
What is a replay camera?
It is a camera, or a phone app, that keeps the last few seconds ready to become a clip. In KplaWY, the phone on a tripod plays that role and you trigger the replay on screen, on a watch, with a Bluetooth button or from another phone.
How many seconds does a replay save?
Up to 10 seconds per replay on the Free plan. KplaWY Pro lets you pick 22, 30 or 50 seconds, useful for long rallies and plays built from the serve.
