Online Timer
Set any custom countdown in minutes and seconds, or pick a quick preset. Free, no signup, with a loud alarm, fullscreen dark display, and a live tab-title countdown.
Quick presets:
A timer for anything
Type any custom duration — minutes and seconds — or tap a preset for common lengths, then press Start. The countdown plays a built-in alarm at zero, updates the browser tab's title live so you can work in another tab, and expands to a large dark fullscreen display for classrooms, workouts, or meetings. Looking for an exact page for a common length? Try the 5 minute timer, 10 minute timer, or 30 minute timer — each is bookmarkable with the duration already set.
