STOPWATCH
Online Stopwatch
A free digital stopwatch with persistent timing, lap statistics and export tools for sports, workouts, study and everyday activities.
The stopwatch session is saved locally in this browser. If it was running, Terbit stores the start timestamp so elapsed time can recover after refresh or browser suspension. Reset clears the saved session.
What is an online stopwatch?
An online stopwatch is a browser-based timing tool that measures elapsed time directly from your device. It helps track duration, intervals and performance without requiring an application download.
How Terbit Clock Stopwatch works
Click Start to begin timing, use Pause when needed and record checkpoints with Lap. A running session stores its start timestamp locally so Terbit can reconstruct elapsed time after a refresh or browser suspension.
Lap statistics and export
Lap measurements help compare separate intervals while keeping the total elapsed time visible. Terbit highlights the best, average and slowest lap, and you can copy the lap summary or download the session as a CSV file.
Common uses for an online stopwatch
Use a stopwatch for running, sports training, workouts, classroom activities, experiments, presentations, cooking and productivity sessions.
Improve productivity with timing
Understanding how long tasks take can improve planning and time management. Combine the stopwatch with Terbit Clock Timer and Alarm Clock tools.
