About this tool
The Auburn AI Stopwatch is a straightforward browser-based timer that measures elapsed time to the millisecond. It includes start, stop, and lap functions, making it useful for athletes, students, developers timing code runs, cooks, or anyone who needs to track how long something takes without installing an app or hunting for their phone.
Reach for this tool when you need a reliable, distraction-free way to time an activity in real time. It works well for interval training, timing presentations, benchmarking manual processes, or recording split times across multiple tasks during a single session.
How to use it
- Open the Stopwatch tool and press Start to begin counting elapsed time immediately.
- Press Lap to record a split time without stopping the main timer.
- Continue adding laps as needed; each split appears in a list below the display.
- Press Stop to pause the timer at any point during your session.
- Press Start again to resume from where you stopped, or Reset to clear everything.
- Copy or note your lap times before resetting, as they clear on refresh.
Pro tips
- Use lap mode to time individual segments of a longer task, then compare splits to spot where time is actually going.
- Keeping this tab open alongside your work tab lets you alt-tab to check elapsed time without breaking focus.
