Why the wrist is the best button
Mid-rally, the phone is far away and your hands are busy. The watch is always in the same place, with a big button that is impossible to miss even at full heart rate.
The gesture becomes reflex in one session: point over, wrist tapped, play saved. Coaches use it too, to tag plays without stopping training.
Apple Watch and Wear OS
KplaWY meets the watch with the app identity and keeps the main action front and center. The screen shows the essentials: buffer status and the REPLAY button.
Keep the watch paired before stepping on court and test one trigger during warm-up. Bluetooth on both sides, no mystery.
No watch: the alternatives
Without a smartwatch, a compatible Bluetooth button in your pocket or a second phone as control on the local network works — a partner on the sideline triggers for you.
Every control talks to the same buffer. Pick what fits your game and keep a backup for long sessions.
Frequently asked questions
Does any smartwatch work?
Apple Watch and Wear OS watches, including Galaxy Watch, are supported, each with its companion app installed.
Does the watch record the video?
No. The phone on the tripod films; the watch is only the remote that fires REPLAY.
What if Bluetooth drops mid-game?
The buffer keeps running on the phone. Reconnect the watch or use the phone button as backup — the seconds stay stored.
