What is the Stopwatch with Laps?
A precise, no-fuss stopwatch that measures time down to the hundredth of a second and records unlimited lap splits. Press Start and the display runs; press Lap at any moment to capture a split without stopping the clock. Every lap is logged in a table with its number, the lap time, and the total elapsed time — and the fastest lap is highlighted green while the slowest is highlighted red, so patterns jump out instantly.
How to use it
- Press Start to begin timing. The button becomes Pause so you can freeze the clock.
- Press Lap whenever you want to mark a split — running, cooking steps, experiment stages.
- Watch the lap table fill up, with your fastest and slowest laps highlighted automatically.
- Press Reset to clear everything back to zero.
Understanding lap times
Each row shows two numbers: the lap time (how long that segment took) and the total (time since you pressed Start). The fastest and slowest highlights compare lap times against each other, which makes it easy to spot your best segment or where you lost time. Highlights appear once you have recorded at least two laps.
Good uses
- Running, cycling and swimming splits.
- Cooking — timing each stage of a recipe.
- Studying or work sprints, alongside the Pomodoro timer.
- Rehearsing speeches and presentations.
