This is a free, no-install digital countdown timer and stopwatch that runs entirely in your browser — no account, no download. Set a countdown or count up, switch between digits or a round dial display, and show a progress bar as time runs out. Click Fullscreen to put it on a second screen, a projector, or a stage monitor. Keyboard shortcuts work too: Space to start or pause, R to reset, F for fullscreen.
It's built by the team behind KUMA Timer, desktop and Raspberry Pi software for running the countdown at conferences, live events and broadcasts — with OSC and Bitfocus Companion control, NDI video output, wireless displays, and remote control from an iPhone or iPad. If you outgrow the browser timer, KUMA Timer's Full tier is a one-off £8 with a 30-day free trial.
