Match timer
A full-screen countdown you can share to every court. Set a duration, hit start, and every device on the link stays in sync. Nothing is saved on our servers.
How it works
- Pick a duration (or a quick preset) and start the timer.
- Share the room link — every device shows the same countdown.
- Start, pause, and ±1:00 adjustments sync to all screens in real time.
- State auto-clears after 24h of inactivity.
FAQ
- Do I need an account?
- No. The timer is a free utility — no signup, no install, no payment.
- How do other devices see the same clock?
- Each timer gets a short room code. Share the link and any device that opens it shows the same countdown in real time — start, pause, and time adjustments sync to everyone.
- Does the clock drift between devices?
- No. Only start/pause/reset/adjustments are sent — each device counts down locally from the shared end time, so every screen stays in lockstep without per-second network chatter.
- Is anything saved?
- No. The timer lives only on the connected devices and a Supabase Realtime channel with nothing at rest. It auto-clears after 24h of inactivity.
