What is a time, and what goes on one?
A time tracker lets you clock in and out of tasks as you work, building an accurate record of how you spend your billable hours. This data feeds directly into timesheets and profitability analysis.
Key components
- Timer controls — start, pause, and stop buttons for real-time tracking.
- Project/client tags — organize time by who it's for.
- Daily/weekly summaries — see how your hours add up.
- Export — pull the data into a timesheet or invoice.
How to use this tool
- Enter the client and project name.
- Click start when you begin working.
- Pause for breaks or interruptions.
- Log the final time entry to your timesheet or invoice.
Why this matters
Even if you bill flat fees, you must know how long tasks take to calculate your real hourly rate. Time tracking is the foundation of accurate estimating and profitability analysis.

Billable time is work you charge clients for. Non-billable includes admin, marketing, and learning. Reports separate these so you can see utilization and true earnings.
A focus method: work in short blocks (often 25 minutes), take a brief break, and after several cycles take a longer break. It reduces fatigue and helps you stay in flow.
Start time and project are saved in localStorage. When you return, the running timer resumes from the saved start timestamp.
Use the edit (pencil) icon next to a session on Today’s list or in the Reports tab to change times, notes, rate, or billable flag.

Billable hours divided by total tracked hours, as a percentage. If 8 of 10 hours were billable, utilization is 80%. Many freelancers aim for strong billable utilization so admin time does not silently erode income.
