About this tool
This free online timer and stopwatch does both: a countdown timer with an alarm sound when time runs out, and a stopwatch with lap times. Use the quick presets (1, 5, 10, 25 minutes) or set your own hours, minutes and seconds.
It runs entirely in your browser — keep the tab open while it counts.
