Running & Athletic Splits
Record lap times without stopping the clock. Each split captures the delta since the last mark and the total elapsed time. Track and field, swim legs, cycling intervals. Hit Lap at each marker and keep going.

Process Timing
How long does a deployment take? A build pipeline? A customer support call from greeting to resolution? Start the stopwatch, mark milestones, stop when it's done. Actual numbers beat estimates every time.
Manufacturing workflows, cooking recipes in development, onboarding walkthroughs. Anything where you need to know how long the steps really take, not how long you think they take.
Presentations & Speeches
Rehearse with the stopwatch running. Lap at each section boundary. You'll know exactly which part runs long before you're standing in front of an audience finding out the hard way.
The timer runs in a Web Worker, so switching to your slides tab won't stop the count.
Lab & Research Timing
Reaction timing, observation intervals, behavioral coding. Centisecond precision (1/100th of a second), calculated from absolute timestamps so there's no drift over long sessions. The display refreshes ten times per second. The timing itself is more accurate than the screen can show.
