This is a real timer. Start it from the admin panel on the left. Watch it update on the display on the right — the same way it works on every screen at your event.

Control from one screen. See it on every other.

Built for the moments that matter most.

When a speaker has 5 minutes left, that information needs to be there. Always. On every screen. Without question.

Offline-first

Your laptop is the server. No internet needed to run, share, or sync. The room's router is the only infrastructure required.

Under 10ms sync

Every display updates in under 10 milliseconds. Direct WebSocket — no cloud relay, no polling, no lag.

Any screen, any device

Projectors, TVs, phones, tablets, second laptops. If it has a browser, it's a display. No app to install.

Designed for distance

Huge glowing digits readable from 20 meters. Color phases shift from green to red as time runs out. Unmissable.

Total control

Presets from 1 minute to 3 hours. Custom durations. Add or subtract time mid-session. Start, pause, reset.

Go online (when you want)

One click creates a public HTTPS link for remote viewers. No account. No setup. Off by default — your timer, your choice.

Up and running in 30 seconds.

The display adapts as time runs out — calm green when there's plenty of time, urgent red when there isn't.

Why not just use a phone timer?

Because a phone timer can't do any of this.
