Smart State Management: The timer automatically tracks your work patterns, including breaks and interruptions, giving you accurate time logs without manual calculations.

Project Organization

Create color-coded projects to categorize your time entries. Each project has a custom color dot that appears throughout the interface — in the entries list, project breakdown, and dropdown selector.

Work

Personal

Default green project for personal activities and hobbies.

Study

Default purple project for learning and educational activities.

Frequently Asked Questions

What happens if I close the browser while the timer is running?

The timer state is automatically saved to your browser's local storage. When you reopen the page, the timer will resume from where it left off, including the correct elapsed time, task description, and selected project. This works even if your browser crashes or your computer restarts.

What is the difference between Pause and Stop?

Pause temporarily stops the timer but keeps the session active — you can resume later and continue accumulating time. Stop finishes the session completely and saves it as a time entry in your list.

Think of Pause as taking a coffee break during a task, and Stop as completing the task entirely. When you stop, the total time (including all paused intervals) is recorded as one entry.

Can I track time for past days?

Yes! Use the Manual Entry button to create entries with any date and time range. This is useful for logging time you forgot to track in real-time, or for entering time tracked through other methods (like paper notes or memory).

Simply fill in the task name, select a project, choose the date, and set the start and end times. The duration will be calculated automatically.

Where is my data stored?

All data is stored in your browser's localStorage — a secure, local storage mechanism built into modern web browsers. Nothing is uploaded to any server or cloud service.

Important: This means your data is private and secure, but it also means clearing your browser data will erase your time entries. Always export your data regularly as a backup.

How do I back up my data?

Use the Export CSV button in the Settings panel to download all your time entries as a CSV file. You can save this file to your computer, cloud storage, or import it into spreadsheet applications like Excel or Google Sheets.

We recommend exporting your data regularly (weekly or monthly) to maintain a backup and for long-term record keeping.

Can I edit or delete a time entry?

Yes! Hover over any entry in the list to reveal edit and delete buttons:

Edit: Click to modify the task name, project, date, or time range. Changes are saved automatically.
Delete: Click to remove the entry permanently. This action cannot be undone, so use it carefully.

This flexibility allows you to correct mistakes, adjust time ranges, or remove duplicate entries.

How does the weekly chart work?

The chart shows the total tracked hours for each of the last 7 days. Today's bar is highlighted with a distinct color to help you quickly identify current progress.

Days with recorded time display proportional bars based on hours tracked, while empty days show a minimal baseline. This visual representation helps you identify productivity patterns, spot gaps in tracking, and maintain consistent time logging habits.

What are the default projects?

Three projects are included by default to help you get started immediately:

Work (blue) — Professional tasks, client projects, and job-related activities
Personal (green) — Personal activities, hobbies, and non-work tasks
Study (purple) — Learning, courses, reading, and educational activities

You can edit these default projects, delete them, or add new custom projects at any time through the Settings panel. Each project can have a unique name and color for easy visual identification.
