Online Timer with History

Measure how long work, study, calls, workouts, or experiments take. Name the session, mark laps, then save a useful history instead of losing the result when you reset.

The important control

Finish & save records the session. Reset intentionally discards it after confirmation.

Count up and remember

Name the task now so the saved history makes sense later.

Up to 100 sessions are stored only in this browser. Clearing site data removes them.

Why this timer keeps history

A stopwatch result should not disappear.

Many quick stopwatches focus on the running display, then erase the context when reset or refreshed. This timer treats the completed session as the useful result: a name, duration, date, laps, and an exportable record.

Names, not mystery rows

Add a simple label such as “Client call” or “Morning run” before saving.

History that is usable

Search sessions, see totals, inspect laps, delete individual records, or clear everything.

Portable when needed

Export CSV for a spreadsheet without creating an account or sending data to a server.

Timer or countdown?

Choose based on the question.

Both tools use timestamps to avoid accumulated tick drift, and both restore active state from this browser.

Timer: “How long did it take?”

Count upward for open-ended work, record intervals, and save the final session to history.

Countdown: “How much time is left?”

Start from a fixed duration and receive a visible and optional audible signal at zero.

Timer history FAQ

What is saved—and what is not.

The history is designed for convenience and privacy, not cross-device account-based time tracking.

How do I save a timer session to history?

Optionally name the task, start the timer, then select Finish & save. The final duration, completion date, and lap marks are added to history and the active timer resets.

Where is my timer history stored?

History is stored in local browser storage on this device. It is not uploaded and does not follow you to another browser. Clearing site data also clears the history.

Will the timer keep counting after a refresh?

Yes. The active session stores its start timestamp, elapsed time, name, and laps. When the page returns, it calculates the elapsed time from those timestamps instead of losing the session.

What is the difference between a lap time and total time?

A lap is the interval since the previous lap mark. Total time is everything elapsed since the session began. This timer shows both and marks the fastest and slowest split after at least two laps.

Can I download my timer history?

Yes. Export CSV downloads session names, completion dates, durations, and lap counts for use in a spreadsheet. No extra package, subscription, or account is required.
