Every freelancer eventually loses money to time they never tracked. Maybe you billed a client for six hours when the project actually ate nine. Maybe you blocked a whole Tuesday for “deep work” and still can’t say where it went. A good time tracking app fixes both problems: it makes your invoices honest and it shows you which clients are quietly unprofitable.
But the market is noisy, and most tools are built for teams of 40, not a team of one. After running a solo business and testing these apps against real client work, I’ve narrowed the field to six that actually fit a freelancer’s workflow — whether you bill by the hour or just want to stop the leaks.

The six best time tracking apps for freelancers at a glance
Here’s the short version before we get into detail. The right pick depends far more on how you bill than on any feature checklist.
| App | Best for | Free plan | Paid from | Standout feature |
|---|---|---|---|---|
| Toggl Track | Hourly billers who hate friction | Yes (up to 5 users) | ~$9/user/mo [CONFIRM] | One-click timer everywhere |
| Clockify | Freelancers on a zero budget | Yes (unlimited tracking) | ~$3.99/user/mo [CONFIRM] | Genuinely usable free tier |
| Harvest | Track-to-invoice in one place | Yes (1 seat, 2 projects) | ~$11/seat/mo [CONFIRM] | Built-in invoicing |
| RescueTime | Fixed-fee work & focus | Limited trial | ~$6.50/mo annual [CONFIRM] | Automatic, passive tracking |
| Timely | People who forget to hit start | No (trial only) | ~$11/user/mo [CONFIRM] | AI drafts your timesheet |
| Everhour | Fans of Asana / Trello / Notion | Free (up to 5 users) | ~$8.50/user/mo [CONFIRM] | Embeds inside your PM tool |
Prices change often, so treat the figures above as a starting point and confirm on each vendor’s pricing page before you commit.
How I judged them (and what freelancers should actually care about)
Team-focused “best time tracker” lists obsess over admin dashboards and payroll exports you’ll never touch. For a solo business, four things matter: how little effort it takes to start a timer, whether it turns tracked time into billable time cleanly, whether the free or entry tier is enough, and whether it fits the tools you already live in. I weighted friction most heavily, because the best tracker is the one you don’t abandon after two weeks.
Toggl Track — the default for hourly freelancers
Toggl Track is the app I recommend first to anyone billing by the hour. The timer lives in a browser extension, a desktop app, and your phone, so starting and stopping is a single click no matter where the work happens. Tag entries by client and project, and at the end of the month you have a clean, defensible record to bill from.
Who it’s for: freelancers who invoice hourly and want the lowest-friction timer on the market. Who should skip it: if you never bill hourly and only want to understand where your day goes, Toggl is more machinery than you need. If you want the head-to-head, see our Toggl vs Clockify comparison. [AFFILIATE: Toggl Track] [PLACEHOLDER: captura del timer de Toggl en la extensión]
Clockify — the best free option, full stop
Clockify’s free plan is the most generous in this roundup: unlimited time tracking, unlimited projects, and reports, at no cost. For a freelancer who just needs to log hours and export a summary, you may never need to pay. Paid tiers add things like billable rates and locked timesheets, but the free version alone beats most competitors’ entry plans.
Who it’s for: anyone starting out or unwilling to add another subscription. Who should skip it: if you want polished invoicing baked in, Clockify makes you export and bill elsewhere. Pair it with our guide on how to track billable hours accurately to get clean numbers from day one. [AFFILIATE: Clockify]
Harvest — track and invoice without switching apps
Harvest’s edge is that it closes the loop: track time against a project, then turn those hours into an invoice inside the same tool, complete with payment links. For a freelancer who currently tracks in one app and invoices in another, collapsing that into one workflow saves real friction every month.
Who it’s for: hourly freelancers who want tracking and billing under one roof. Who should skip it: if you already have an invoicing tool you love, you’re paying for overlap. The free tier (one seat, two projects) is enough to trial the full flow before upgrading. [AFFILIATE: Harvest]

RescueTime — for fixed-fee work and focus
RescueTime is the odd one out, and that’s the point. Instead of asking you to start a timer, it runs in the background and categorizes where your attention actually goes — which apps, which sites, how much focused time versus distraction. If you bill fixed fees, you don’t need billable hours; you need to know which projects are silently eating your week so you can price the next one properly.
Who it’s for: fixed-fee freelancers and anyone fighting distraction. Who should skip it: if you need per-client billable records, passive tracking won’t give you the itemized log an invoice requires.
Timely — when you always forget to hit start
Timely (from Memory AI) records your activity automatically and then uses AI to draft timesheet entries you approve or edit. It’s the answer to the single biggest failure mode in time tracking: forgetting to press the button. You still get billable, client-tagged entries, but the first draft is written for you.
Who it’s for: freelancers who know manual tracking never sticks for them. Who should skip it: the privacy-conscious, and anyone unwilling to pay — there’s no free tier, only a trial. [AFFILIATE: Timely]
Everhour — if you live inside a project tool
Everhour embeds a timer directly into Asana, Trello, ClickUp, Notion, and similar tools, so tracking happens where you already manage tasks instead of in a separate window. If your workflow is anchored to a project board, this removes the context-switch entirely. If you’re weighing those boards themselves, our ClickUp vs Notion breakdown pairs well with this.
Who it’s for: freelancers built around a PM tool. Who should skip it: if you don’t use one of its integrations, a standalone timer like Toggl is simpler. [AFFILIATE: Everhour]
Free vs paid: what a freelancer really needs
Most solo businesses over-buy here. If you bill hourly and want zero cost, Clockify’s free plan covers you. If you’ll pay a little for less friction and cleaner billing, Toggl Track or Harvest earn it. Only reach for a passive tracker like RescueTime or Timely when the real problem is not knowing where your time goes rather than logging hours to bill. Buying the wrong category is the most common (and expensive) mistake. For the wider stack, see our best software for freelancers guide and the rest of the time tracking & project management silo.
The verdict: which one should you pick?
For most hourly freelancers, Toggl Track is the safest first pick — low friction and a free tier to start. If budget is the priority, Clockify’s free plan is unbeatable. If you invoice from your tracked hours, Harvest saves you an app. And if your problem is fixed-fee profitability or forgetting to track at all, go straight to RescueTime or Timely. Match the tool to how you bill, not to the longest feature list, and you’ll actually keep using it.

Frequently asked questions
What is the best free time tracking app for freelancers?
Clockify has the most generous free plan — unlimited time tracking, projects, and reports at no cost. Toggl Track and Harvest also offer free tiers, but with tighter limits on users or projects.
Do I need a time tracker if I charge fixed fees?
Yes, but for a different reason. You’re not billing the hours, you’re protecting your profit. A passive tracker like RescueTime shows which fixed-fee projects consume the most time so you can price future work more accurately.
Which time tracking app has built-in invoicing?
Harvest is the strongest option here: it turns tracked hours into invoices with payment links inside the same tool, so you don’t need a separate billing app.
What if I always forget to start the timer?
Choose an automatic tracker. Timely records your activity in the background and drafts timesheet entries with AI, while RescueTime categorizes your time passively. Both remove the “forgot to hit start” failure mode.
Can I track time inside my project management tool?
Yes. Everhour embeds a timer directly into Asana, Trello, ClickUp, and Notion, so you track without leaving the board you already work in.
Is a paid time tracker worth it for a solo freelancer?
Only if it removes friction or replaces another subscription. If you bill hourly and want zero cost, a free plan is usually enough. Pay when cleaner billing or automatic tracking clearly saves you time each month.
