What is a Stopwatch?

A stopwatch is a timing utility that measures elapsed time from a starting point. It is commonly used for workouts, study sessions, races, productivity tracking, and performance measurements.

How to Use

  1. Press Start to begin measuring elapsed time.
  2. Use Lap when you need to save section time and total elapsed time.
  3. After stopping, copy lap records or copy a share link to keep the result.
  4. Load previous sessions from Recent Records or use Focus Mode for a larger timer view.
Workout Timing

Measure set breaks, running laps, interval training, and exercise sections while comparing each lap.

Study Focus

Use focus mode to track study blocks, problem-solving time, and break periods without extra clutter.

Task Tracking

Track task duration, meeting time, and repeated work sessions, then copy records for a simple work log.

What is a lap record?

A lap record stores the time between the previous lap and the current lap. It helps compare individual sections while also keeping track of the total elapsed time.

How does sharing work?

The share feature generates a URL containing the current stopwatch record and lap information. Opening the link restores the same record.

Where are recent records stored?

Recent stopwatch records are stored in your browser's local storage. They are not uploaded to a server and are only available in the same browser.
