So nutzt du: Time Tracker

  1. Type what you’re working on, pick a project and press Start. The timer keeps running if you close the tab.
  2. Press Stop when you finish. Edit the note right in the list, change times with the pencil, or continue an entry with ▶.
  3. Forgot to start the timer? Use Add time manually with a start and end time.
  4. Set hourly rates under Projects & rates, choose a period, and export a CSV, Excel or PDF timesheet.

A private time tracker that works without an account

Most time trackers want you to sign up first. This one starts the moment the page loads: your projects, entries and notes are saved in your browser’s local storage and never sent to a server. A running timer survives closing the tab or restarting the browser, and the page title shows the elapsed time so you can see it from any tab.

  • Projects with colors and hourly rates — billable time turns into earnings in the summary and exports.
  • Notes on every entry, editable in place, so your timesheet says what the hours were for.
  • Daily and weekly totals, a per-project breakdown and filters for today, this week, last week and this month.
  • Rounding to 1, 5, 6 (a tenth of an hour), 15 or 30 minutes for invoices.
  • Exports: CSV for any spreadsheet, a real Excel .xlsx file and a printable PDF timesheet. Download a JSON backup to move your data to another browser.

Timesheet tips for freelancers

Track as you work rather than reconstructing the day afterwards — estimates from memory are usually off by a lot. Write a short note per entry (“Homepage hero, review round 2”) so clients can see what they’re paying for. Round consistently, and say in your contract which rounding you use.

Keep your data safe

Because everything lives in this browser, clearing site data or using a private window removes it. Download a backup now and then, especially before switching computers.

Häufige Fragen

Is this time tracker free?
Yes. There’s no account, no limit on projects or entries and no paid plan. It runs in your browser.
Where is my data stored?
In your browser’s local storage on this device. Nothing is uploaded. Use Download backup to keep a copy or move your entries to another browser, then Restore backup there.
Does the timer keep running if I close the tab?
Yes. The start time is saved, so when you come back the timer shows the full elapsed time. Stop it whenever you finish.
Can I export a timesheet?
Yes: CSV, an Excel .xlsx file or a PDF timesheet for the selected period and project, with notes, durations, billable hours and earnings.
How does rounding work?
Pick a rounding step for reports, for example 15 minutes. Each entry’s duration is rounded to the nearest step in the totals and exports; the original times are kept.
Kann ich Time Tracker als Web-App installieren und offline nutzen?
Ja. Time Tracker ist eine installierbare Web-App (PWA) – sie wird über Ihren Browser installiert und nicht aus einem App-Store heruntergeladen. Klicken Sie oben auf dieser Seite in Chrome oder Edge (Windows, macOS, Linux, ChromeOS) auf „App installieren“ oder verwenden Sie auf Android-Geräten „Teilen“ → „Zum Startbildschirm hinzufügen“ auf dem iPhone und iPad bzw. „Datei“ → „Zum Dock hinzufügen“ in Safari 17+ auf einem Mac. Die App öffnet sich dann in einem eigenen Fenster mit einem eigenen Symbol, und da sie vollständig in Ihrem Browser ausgeführt wird, funktioniert sie auch offline. Firefox auf dem Desktop kann keine Web-Apps installieren. So funktioniert die Installation.
