Stopwatch & Timer

Stopwatch with laps; countdown with alarm.

A precise, drift-free stopwatch with lap times, and a countdown timer with minute and second inputs, quick presets (1, 5, 10 and 25 minutes) and an audible alarm when it reaches zero. The countdown keeps running while the tab is in the background.
