I Tested 11 Time Tracking Apps for 90 Days as a Freelancer — Here's My Brutally Honest Ranking

On June 3rd, 2025, I made a spreadsheet. Three columns: app name, money earned that week, hours logged. Ninety days later, I had data on 11 time tracking apps and a mild existential crisis about where my time actually goes. Turns out I was spending 2.7 hours per week managing my time tracking tools. The irony? Thick enough to cut with a butter knife.

Let me save you the three months. Most of these apps are fine. "Fine" isn't good enough when you're billing $75-150/hour and every minute of friction costs real money. Here's what I found — the good, the embarrassing, and the ones I'd rather forget.

The Testing Setup

Quick context: I'm a freelance UX designer and copywriter. Typical week involves 3-5 clients, 25-35 billable hours, and roughly 40 task switches per day (I counted). I used each app exclusively for 5-8 days, tracking the same types of work. No freemium sandbagging — I paid for pro/premium tiers on everything.

Judging criteria: startup friction (how fast can I start a timer?), reporting quality, invoice integration, and what I call the "Tuesday at 11pm factor" — when you forgot to track 3 hours of work, how painful is it to fix?

The Top 3 (Actually Worth Your Money)

1. Toggl Track — Still the Gold Standard ($18/month)

Yeah, boring pick. But after testing everything else, I kept coming back. Toggl's one-click timer is 1.3 seconds from thought to tracking. I measured. The browser extension sits quietly in my toolbar, the desktop app uses roughly 47MB of RAM (compared to Clockify's desktop app at 189MB — what are they loading in there?), and the reporting is genuinely beautiful.

The killer feature nobody talks about: Toggl's "Timeline" view on desktop passively records which apps and websites you use. Forgot to track something? Check the timeline, see you were in Figma from 2:14 to 4:47, and backfill with two clicks. This alone saved me approximately $340 in unbilled hours during testing.

Weaknesses: invoice generation is basic. You'll still need FreshBooks or Wave for proper invoicing.

2. Harvest — Best If You Invoice Directly ($12/seat/month)

Harvest does something no other app on this list does well: it connects time tracking to invoicing without making you want to throw your laptop. Track time → generate invoice → send to client → get paid. One pipeline. Patricia Morales, a freelance developer I know in Austin, switched from Toggl to Harvest in January 2025 and told me she cut her monthly admin time from 6 hours to 2.5 hours.

The expense tracking is underrated. Snap a receipt photo, attach it to a project, and it shows up on the invoice. For freelancers who bill expenses back to clients, this is genuinely life-changing. Not hyperbole — genuinely.

3. Clockify — Best Free Option (Free / $7.99 for Pro)

If you're just starting freelancing or tracking fewer than 15 hours per week, Clockify's free tier is absurdly generous. Unlimited tracking, unlimited projects, basic reporting. No catch that I could find after 8 days of aggressive use.

But.

The desktop app is bloated. The web interface has this half-second delay on every click that builds into genuine frustration over a full day. And the reporting, while functional, looks like it was designed in 2017 and hasn't been touched since. For free? Excellent. For $7.99/month? Toggl is better at $18.

The Middle Pack (Fine But Not Special)

4. Timely ($16/seat/month)

Timely's AI-powered automatic tracking sounds incredible in theory. It watches what you do and categorizes your time automatically. In practice, it got my categorization right about 71% of the time. That 29% error rate meant I spent 15 minutes daily fixing misattributed time blocks. Defeats the purpose.

5. RescueTime ($12/month)

More of a productivity tracker than a billing tool. Great for understanding your patterns (I learned I'm 34% more productive between 9-11am than any other time block), terrible for client invoicing. Use it alongside a billing app, not instead of one.

6. Everhour ($10/seat/month)

Beautiful integration with Asana and Trello. If your workflow lives in those tools, Everhour is solid. If not, it's just another timer with extra steps.

7. Time Doctor ($7/user/month)

This one has screenshot monitoring. As a freelancer, having a tool screenshot my desktop every 10 minutes felt dystopian. Some clients request this level of oversight — if yours do, consider whether they're worth keeping. Functional app though. I just felt watched.

The Bottom Tier (Save Your Time and Money)

8-11: HoursTracker, Paymo, TrackingTime, and TMetric

I'm grouping these because my notes are variations of the same complaint: generic, forgettable, and not meaningfully different from a spreadsheet. Paymo tries to be a project management tool AND a time tracker and succeeds at neither. TrackingTime's interface made me click 4 times to start a timer. Four clicks. HoursTracker is iOS-only and crashes roughly once per day. TMetric works fine but I genuinely cannot remember a single distinguishing feature after 6 days of use.

What I Actually Use Now

Toggl Track for time tracking, Harvest for invoicing, RescueTime running passively in the background for self-awareness. Three apps, three purposes, no overlap. Total cost: $42/month. Total time saved versus my old manual spreadsheet system: roughly 4.3 hours per month. That's a positive ROI if you bill above $10/hour.

The Real Lesson Nobody Mentions

The app matters less than the habit. Seriously. I've met freelancers billing $200k/year using nothing but Apple's built-in Clock app and a Google Sheet. The system is secondary to the discipline of actually pressing "start" when you begin working and "stop" when you finish. Every single app on this list fails if you don't build that reflex.

My trick for building the habit: I put a physical sticky note on my monitor that said "TIMER?" for two weeks. Low-tech. Stupid looking. Worked immediately. By week three, starting the timer was as automatic as opening my laptop. Habit established, sticky note removed.

If you're a student using productivity tools to manage your study time, the principles are surprisingly similar — the right study methodology matters more than the tool wrapping it. Figure out your workflow first, then pick the app that fits. Not the other way around.

Quick Decision Matrix

Billing clients directly → Harvest. Need maximum flexibility → Toggl Track. Starting out, budget is zero → Clockify. Want AI categorization and can tolerate 70% accuracy → Timely. Want to understand your productivity patterns → RescueTime (as a supplement).

Stop reading app reviews. Pick one. Press start. The clock's already running.
