A free time tracking app for freelancers is a lightweight tool that logs hours across multiple clients and projects without charging a monthly subscription.
Freelancers lose an average of four billable hours per week to untracked work. That adds up to over 200 hours a year. At even modest rates, this represents thousands in lost revenue. The right tracker changes this math quickly.
We tested the four most popular free time tracking tools against a real multi-client workflow. Clockify wins for unlimited tracking on a free plan. Toggl Track is best if you need polished reports. Harvest suits those who want invoicing built in. Hubstaff fits freelancers who need activity monitoring.
Key facts: Clockify offers unlimited users and projects on its free tier. Toggl Track limits free users to five seats and basic reporting. Harvest caps free tracking at two projects and one seat. Hubstaff provides a free plan with limited activity screenshots. All four export data, but only Harvest generates invoices directly from tracked hours on the free plan.
| Feature | Toggl Track | Clockify | Harvest | Hubstaff |
|---|---|---|---|---|
| Free users limit | 5 | Unlimited | 1 | 1 |
| Projects on free | Unlimited | Unlimited | 2 | Unlimited |
| Invoicing on free | No | No | Yes (limited) | No |
| Idle detection | Yes | Yes | No | Yes |
| Mobile apps | iOS, Android | iOS, Android | iOS, Android | iOS, Android |
| Export formats | CSV, PDF | CSV, PDF | PDF, CSV | CSV, PDF |
| Paid plan starts at | $9/mo | $3.99/mo | $12/mo | $4.99/mo |
Freelancers who track time bill 19% more on average than those who do not.
Where most guides get this wrong
Most guides treat free plans as equal. They are not. Some cap projects. Others cap team seats. Many hide invoicing behind paywalls.
Freelancers with multiple clients get burned by project limits first. Harvest restricts free accounts to two active projects. Once a third client signs, the clock stops working. Clockify and Toggl Track avoid this trap with unlimited projects.
Team-seat limits matter less for solopreneurs but cap future growth. Toggl Track caps free teams at five seats. That sounds generous until you bring on a subcontractor or virtual assistant. Clockify removes this ceiling entirely.
The real constraint is export access. If you cannot get your data out in a portable format, the free plan becomes a trap. All four tools here export CSV or PDF, which means you can leave without rebuilding your records.
Toggl Track: best for polished reporting and ease of use
Toggl Track has the cleanest interface in this group. The one-click timer starts instantly. The project picker sits front and center. New users learn it in minutes without a tutorial.
Reporting on the free plan is basic but readable. Weekly summaries break down hours by project and client. Exported PDFs look professional enough to send to clients directly.
The five-seat limit on the free tier is generous for solo freelancers. You can add a subcontractor and still have room. Beyond five people, the $9/mo paid plan unlocks billable rates and project forecasts.
Toggl Track does not generate invoices on the free plan. You must export hours and bill elsewhere. Pair it with a free invoicing tool to close the gap.
Clockify: best overall free plan for multi-client freelancers
Clockify offers the most generous free tier in this comparison. Unlimited users, unlimited projects, unlimited tracking. No seat caps. No project walls.
The timer works the same way as Toggl Track. You pick a project, type a description, and start the clock. Idle detection prompts you to discard or keep inactive time.
Reporting goes deeper than the other free options. Weekly and monthly summaries break down billable versus non-billable hours. Client-level summaries show where your time actually goes.
Invoicing is not included on the free plan. The paid plan starts at $3.99/mo and unlocks invoicing plus billable rates. For freelancers who need to track many clients without paying, Clockify is the default choice.
Harvest: best if invoicing matters more than tracking depth
Harvest is the only tool here that generates invoices directly from tracked time on its free plan. Hours flow into a draft invoice with one click. That workflow saves 15 to 30 minutes per billing cycle.
The catch is the two-project limit. Freelancers juggling three or more active clients will hit this wall fast. Each project counts, even archived ones you keep for records.
Harvest also limits free accounts to one user. No team access. No subcontractor seats. For a true solo freelancer with two ongoing clients, this tradeoff can work.
The invoicing integration is what justifies choosing Harvest despite the constraints. Learn more about tracking billable hours with free tools to see how the export-to-invoice path works.
Hubstaff: best for activity-verified timesheets
Hubstaff takes a different approach. Beyond a simple timer, it captures activity levels, app usage, and periodic screenshots. This data proves work happened, not just that time was logged.
The free plan includes basic time tracking plus limited activity screenshots. Paid plans unlock deeper monitoring, geofencing, and payroll features. For freelancers who bill by the hour and face skeptical clients, Hubstaff provides receipts.
The free plan supports one user and unlimited projects. There is no invoicing on the free tier. Exported reports work with lightweight client management tools to bridge the gap.
How to set up your free time tracker in under 20 minutes
- Pick your primary tool based on the verdict that matches your workflow. Clockify for multi-client tracking, Harvest for built-in invoicing, Toggl Track for clean reporting, or Hubstaff for verified activity.
- Create an account and set your time zone first. Wrong time zones shift logged hours and confuse client reports.
- Add every active client as a separate project or client label. Do not lump multiple clients under one project. Clean separation makes invoicing painless later.
- Enable idle detection if available. This prevents phantom hours from inflating your timesheet and protects your credibility with clients.
- Run a three-day test. Track your real work. Export the report. If the export looks clean and the invoice path is clear, commit to the tool for 30 days.
Final decision path
If you track hours across three or more clients and need a truly free tier, pick Clockify. Its unlimited projects and users remove every wall that would force you onto a paid plan.
If you invoice clients directly from tracked time and only serve two projects at once, pick Harvest. The built-in invoice generator saves real administrative time each billing cycle.
If you value a polished interface and readable weekly reports above all else, pick Toggl Track. It is the easiest tool to learn and the fastest to start using on day one.
If you bill skeptical clients and need to prove work activity, pick Hubstaff. Screenshots and activity levels provide a layer of trust that plain timers cannot match.
