A timer for projecting in talks, classes and meetings. Set the time and press Start. It's the same clock on every screen: anyone with the link sees it and controls it in real time, from another computer or from their phone.
Project opens a tab that shows only the clock, for the projector or the screen in the room, while you control it from yours. That link has no buttons, so you can share it with anyone. The one in your own tab does control it: give it only to whoever will run it.
If what you have is an end time rather than a duration, pick it under Until and the clock counts down to it. Either way, the limit is one hour.
It works without an account. A timer nobody uses for 30 days deletes itself.
I needed a big clock on one screen and the controls on another. The ones I found were full of ads, asked me to sign up, or lived in a single tab with no way to run them from anywhere else.
So I made this one.
Tell me through . Ideas for improvements too. I read every one.
