Every unbilled hour is money you earned and never collected, and freelancers lose an average of 204 hours a year to admin and untracked work. A free time tracker closes that gap: one click starts a timer, and the report at month end becomes your invoice. Toggl Track and Clockify are the two best free options, and they suit different kinds of freelancers. This comparison settles which one fits you.

Toggl Track: The Fast, Familiar Timer

Toggl Track wins on speed: one click starts a timer from your browser, desktop or phone, and the free plan covers up to three users with unlimited time entries. The browser extension works inside most tools you already use, and reports split neatly by client and project for invoicing. Billable rates and profitability reports are paid features, and the free plan can turn a report into a PDF invoice, though with Toggl's logo on it. Toggl is the best choice if you want the simplest possible timer.

Clockify: The Free All-Rounder

Clockify's free plan is unusually generous: unlimited time tracking, projects and tasks for up to five users, with timesheets and basic reports included. It is the better choice if you manage multiple clients and projects and want everything in one place. The free reports cover a limited history, so export your numbers monthly, and invoicing sits on paid tiers. Clockify's interface is busier than Toggl's, but the extra structure pays off once you track more than two clients.

Other Free Options Worth Knowing

Harvest offers a free plan with excellent client-ready invoices, though the free tier is limited to one user and two projects. FreshBooks bundles time tracking with invoicing and expenses, and its plans start around $9.20 a month. Timen is a genuinely free all-in-one that covers tracking, reporting and invoicing with no per-seat charge. If your main problem is invoicing rather than tracking, start with Harvest or Timen instead.

Which One Should You Choose?

Choose Toggl Track if you are a solo freelancer who wants the fastest timer and the cleanest reports. Choose Clockify if you juggle several clients and projects and want free timesheets and unlimited entries. Either way, the tool matters less than the habit: track every working hour for a month, and the report will show you exactly where your time goes. Most freelancers discover they bill 20-30% fewer hours than they work.

Making Time Tracking Stick

The habit fails when tracking feels like admin. Keep the timer visible, start it before you start working, and review the week every Friday for five minutes. Tag every entry by client and project so the month-end invoice writes itself. After a month, compare tracked hours with billed hours: the gap is your raise, and closing it is the fastest pay rise in freelancing.

Tracking Time for Fixed-Price Work

Time tracking matters even when you charge by the project, because it tells you whether the project was profitable. A project that paid $500 and took 20 hours earned $25 an hour, while the same fee for 10 hours earned $50, and that difference decides whether you take similar work again. Track time on every project, even fixed-price ones, and review the hourly rate monthly. The data will surprise you: most freelancers discover that their best-paying work is not the work with the highest fee, but the work with the highest effective hourly rate.

Key Takeaways

- Toggl Track is the fastest timer; Clockify is the most generous free all-rounder - Both free plans cover solo freelancers completely - Harvest and Timen are better if invoicing is your main problem - Most freelancers bill 20-30% fewer hours than they actually work
