Thanks for using the TED Countdown Timer — the same one designed for use at the TED Conference — to rehearse and time your own TED Talk!

Get it

The TED Countdown Timer is free to use, and can be accessed through any Web browser. Using Chrome’s Presentation Mode allows you to focus only on the timer. If you want to use the Timer like an app on your mobile device, tap on the share icon (iOS) or menu button (Android) and select “Add to Home Screen.”

Use it

To start the Timer, select the duration of your talk (choose any length from 2 to 18 minutes). Next hit 'Start now' to begin the countdown immediately, or 'Start in 10 seconds' to give yourself time to get ready.

For a less distracting countdown, the Timer initially displays minutes only — for example, a 14-minute talk will flash “14” to start, then display “13” for the next 60 seconds, then “12,” and so on. The dots along the bottom show your progress through each minute (each dot represents six seconds).

The Timer will switch to a second-by-second countdown at 90 seconds. If you go over your chosen time, the Timer screen will turn red, flash 'OVER TIME,' and begin counting up.

To pause the Timer, use the button in the lower right corner; if you're on a laptop or desktop machine, move your mouse to make the pause button appear.
