Online Stopwatch
Counts up from zero · start, pause, reset · no signup.
A stopwatch counts up from zero, so you can measure how long something takes rather than counting down to a deadline. Press start and the flip clock ticks forward; pause and resume any time.
Run it fullscreen for a big, readable display — handy for workouts, timing laps, games, or anything you want to measure across the room.
Tip: Need a countdown instead of a count-up? Use one of the preset timers below — they start at a set time and count down to zero with a chime.
