I’ve been testing time tracking apps on and off for about four years now. Some of that was for freelancing, some for curiosity, and honestly some because I kept losing track of where my workday went. After putting eight popular options through real daily use over the last month, here’s what I found.
Quick Comparison
| App | Best For | Free Plan | Starting Price |
|---|---|---|---|
| Toggl Track | Freelancers and small teams | Yes (up to 5 users) | $9/user/mo |
| Clockify | Budget-conscious teams | Yes (unlimited users) | $3.99/user/mo |
| Harvest | Invoicing + time tracking | Yes (1 user, 2 projects) | $10.80/user/mo |
| RescueTime | Automatic tracking | Yes (limited) | $12/mo |
| Hubstaff | Remote team monitoring | Yes (1 user) | $4.99/user/mo |
| Timely | AI-powered auto-tracking | 14-day trial | $9/user/mo |
| TrackingTime | Project-based teams | Yes (up to 3 users) | $5/user/mo |
| Kimai | Self-hosted open source | Yes (self-hosted) | Free / cloud from €9/mo |
1. Toggl Track – Best Overall for Most People
Toggl has been around forever and there’s a reason it keeps showing up in these lists. The interface is dead simple. You click start, you click stop. That’s it. No onboarding tutorial needed.
What I like most is the browser extension. It integrates with something like 100+ tools – Trello, Asana, GitHub, Jira, you name it. So you can start a timer right from your project management tool without switching tabs.
The free plan covers up to 5 team members with unlimited tracking. For a freelancer or small agency, that’s genuinely enough. You get basic reports, project tracking, and the desktop/mobile apps.
Where it falls short
Reporting on the free tier is pretty basic. If you need detailed breakdowns by client, billable vs non-billable hours, or labor cost analysis, you’re looking at the Starter plan at $9/user/month. The jump from free to paid feels steep for what you get.
Also, there’s no screenshot or activity monitoring. If your boss wants proof you were actually working, Toggl won’t help with that (which honestly I see as a feature, not a bug).
Pros
- Extremely easy to pick up and use
- Huge list of integrations
- Solid free plan for small teams
- Works on every platform including Linux
Cons
- Paid plans get expensive for larger teams
- Free reporting is limited
- No invoicing built in
2. Clockify – Best Free Option (No Catches)
Here’s the thing about Clockify – the free plan has unlimited users. That’s not a typo. Most competitors cap you at 1-5 users on free tiers, but Clockify just… doesn’t. I’ve seen teams of 20+ people using it without paying a cent.
The tracking itself works well. Timer mode, manual entry, calendar view, timesheet view. It covers the basics without overcomplicating things. Reports are decent on the free plan too – you can filter by project, team member, date range, and export to PDF or CSV.
I used Clockify for about six months when I was freelancing. It did everything I needed for tracking billable hours across four clients. The weekly timesheet view was my go-to because it let me fill in time after the fact (I’m terrible at remembering to start timers).
The catch (sort of)
While the free plan is generous, some features you’d expect are locked behind paid tiers. Time off tracking, invoicing, custom fields, GPS tracking – all paid. The interface also feels a bit cluttered compared to Toggl. More buttons, more menus, more stuff competing for your attention.
Pros
- Unlimited users on free plan
- Decent reporting without paying
- Timesheet view is great for manual entry
- Kiosk mode for physical workplaces
Cons
- Interface feels busy
- Invoicing requires paid plan
- Mobile app can be sluggish
3. Harvest – Best for Freelancers Who Invoice
If you track time specifically to bill clients, Harvest connects those dots better than anyone else. You track hours, assign them to projects, and generate invoices directly from that data. No exporting to a spreadsheet, no copy-pasting numbers. It just flows.
The invoicing integration with Stripe and PayPal means clients can pay directly from the invoice email. During my testing, I sent an invoice and got paid within 2 hours. That’s the kind of friction reduction that actually matters for cash flow.
Harvest also has solid project management features built in. Budget tracking per project, capacity planning, cost rates vs bill rates – it’s clearly built for service businesses and agencies.
The downside
The free plan is almost useless – 1 user, 2 projects. That’s basically a demo. And at $10.80/user/month, it’s one of the pricier options. For solo freelancers juggling multiple clients, you’ll outgrow the free plan immediately.
The UI also hasn’t changed much in years. It works fine, but it looks dated compared to newer tools. Not a dealbreaker, but worth mentioning.
Pros
- Best-in-class invoicing integration
- Budget and capacity tracking
- Direct payment through invoices
- Solid QuickBooks and Xero sync
Cons
- Free plan is very limited
- On the expensive side
- Dated interface design
4. RescueTime – Best for Automatic Tracking
RescueTime takes a completely different approach. You don’t press start or stop. You install it, and it runs in the background, logging which apps and websites you use throughout the day. Then it categorizes everything as productive, neutral, or distracting.
This was eye-opening for me. I thought I spent maybe 30 minutes a day on Slack. RescueTime showed me it was closer to 2 hours. That kind of data changes behavior fast.
The daily/weekly reports break down your time into categories and give you a productivity score. You can set goals like “spend less than 1 hour on social media” or “spend at least 4 hours on development” and it tracks your progress automatically.
Not for everyone
If you need to track time against specific client projects for billing, RescueTime isn’t the right tool. It tracks app usage, not project time. You can manually assign time blocks to projects, but it defeats the purpose of automatic tracking.
Privacy is also a consideration. Having software log every website you visit and app you open makes some people uncomfortable. The data stays on their servers (or locally with the premium plan), but it’s worth thinking about.
Pros
- Zero-effort automatic tracking
- Genuinely useful productivity insights
- Focus sessions block distracting sites
Cons
- Can’t track billable project hours well
- Privacy concerns for some users
- Free plan was recently stripped down
- No team features on lower plans
5. Hubstaff – Best for Remote Team Monitoring
Hubstaff is what you get when a company wants employee monitoring disguised as time tracking. And look, I’m not saying that’s always a bad thing. If you manage a remote team of contractors and need to verify hours billed, Hubstaff does that job well.
It takes optional screenshots at random intervals, tracks mouse and keyboard activity levels, and even offers GPS tracking for field workers. The dashboard shows you who’s working, what they’re working on, and how active they are – all in real time.
For legitimate use cases like managing overseas development teams or tracking field service workers, this level of visibility can be worth it. The automatic payroll feature based on tracked hours is also pretty slick – it connects to PayPal, Payoneer, or direct bank transfers.
The surveillance problem
Let’s be real – many employees hate this type of software. The screenshot feature especially feels invasive. If you use this with an in-house team, expect pushback. My recommendation: only enable the features you actually need. Activity tracking without screenshots is a reasonable middle ground.
The pricing starts reasonable at $4.99/user/month but gets complicated with add-ons. GPS, app tracking, and idle timeout settings each come at different tier levels. Read the plan comparison carefully before committing.
Pros
- Detailed activity and productivity reports
- Built-in payroll processing
- GPS tracking for mobile teams
- Good integration with PM tools
Cons
- Feels like surveillance software
- Pricing tiers are confusing
- Can hurt team trust if misused
6. Timely – Best AI-Powered Tracking
Timely’s pitch is that you should never have to manually log time again. Its AI (called Memory) records everything you do in the background – meetings, documents, emails, apps, websites – and drafts time entries for you. You just review and approve them.
After two weeks of use, I’d say the AI gets it right about 70-80% of the time. It correctly identified my coding sessions, Zoom calls, and Google Docs work. Where it struggled was with context – it knew I was in VS Code for 3 hours but couldn’t tell which project I was working on.
The timeline view is beautiful though. Seeing your entire day laid out with color-coded blocks is genuinely satisfying. And the auto-draft feature saves me roughly 15-20 minutes per day compared to manual logging.
The price tag
No free plan – just a 14-day trial. Starting at $9/user/month with a minimum of 5 users on some plans, this is firmly in the “established teams” category. Solo freelancers should look elsewhere.
Pros
- AI auto-drafts save real time
- Beautiful timeline interface
- Strong privacy focus (data visible only to user)
Cons
- No free plan
- AI accuracy isn’t perfect
- Expensive for small teams
- Minimum user requirements on some plans
7. TrackingTime – Best for Project-Based Teams
TrackingTime flies under the radar compared to Toggl and Clockify, but it has some neat tricks. The project-centric approach means everything revolves around tasks and projects rather than just time entries. You create projects, break them into tasks, and track time against specific tasks.
What sets it apart is the planning feature. You can estimate how long tasks should take and then compare estimates vs actuals. Over time, this helps you get better at scoping work – something most freelancers and agencies struggle with.
The free plan supports up to 3 users with unlimited projects and tasks. That’s tight but workable for a tiny team. Reports are solid and include utilization rates, which show you how much of your team’s capacity is being used productively.
Pros
- Strong project and task organization
- Estimate vs actual comparison
- Clean, modern interface
- Good Trello and Asana integration
Cons
- Free plan limited to 3 users
- Less known, smaller community
- Mobile app needs work
8. Kimai – Best Self-Hosted Open Source
If you want full control over your data and don’t mind getting your hands a bit dirty with setup, Kimai is worth a look. It’s open source, self-hosted, and completely free if you run it on your own server.
I set it up on a cheap VPS in about 20 minutes (it’s a PHP/Symfony app, so standard web hosting works). The feature set is surprisingly complete – multi-user, project tracking, invoicing, reporting, API access, and a plugin system for extensions.
For agencies or businesses with strict data residency requirements, self-hosting means your time tracking data never leaves your infrastructure. That’s a real selling point for European companies dealing with GDPR or anyone working with sensitive client data.
The tradeoff
You need to maintain it yourself. Updates, backups, security patches – that’s on you. The cloud-hosted version starts at €9/month per user and handles all that, but at that price point, you might as well look at Toggl or Harvest.
The UI is functional but not pretty. It gets the job done without any visual flair. If your team cares about aesthetics (and many do), this could be a hard sell.
Pros
- Completely free and open source
- Full data ownership and privacy
- Active development community
- Plugin system for customization
Cons
- Requires self-hosting knowledge
- UI looks dated
- No native mobile app (web app only)
- Smaller integration ecosystem
How I Tested These Apps
I used each app as my primary time tracker for 3-5 days during regular work. My workflow includes coding (VS Code, terminal), communication (Slack, email), meetings (Zoom), and writing (Google Docs, Notion). I tested on macOS with Chrome, plus the iOS app for each tool where available.
I looked at: how fast can I start tracking? How accurate is the data? How useful are the reports? And the big one – did I actually remember to use it consistently?
Which One Should You Pick?
For most individuals and small teams: Toggl Track. The free plan is generous, the UX is clean, and the integrations mean it fits into whatever workflow you already have.
If budget is tight and your team is bigger: Clockify. Unlimited free users is hard to argue with.
If you bill clients by the hour: Harvest. The time-to-invoice pipeline alone saves hours per month.
If you hate manual tracking: RescueTime for personal productivity insights or Timely for team project tracking.
If you manage remote contractors: Hubstaff, but please use the monitoring features responsibly.
If you want full data control: Kimai self-hosted.
FAQ
Are free time tracking apps actually free?
Clockify and Toggl both have genuinely usable free tiers. Clockify’s is the most generous with unlimited users. Most others limit you to 1-2 users or basic features on free plans, which works for solo use but not teams.
Can my employer see everything I do with time tracking software?
Depends on the tool and settings. Hubstaff with screenshots enabled shows a lot. Toggl and Clockify only show what you manually track – they don’t monitor your screen. Always ask your employer what features are enabled.
Do time tracking apps actually improve productivity?
In my experience, yes, but mainly through awareness. When you see hard data showing you spent 3 hours on email, you start making changes. The tracking itself doesn’t make you productive – the insights do.
What’s the best time tracking app for freelancers?
Toggl Track for simplicity, or Harvest if invoicing is a priority. Both have good free tiers for solo users, though Harvest’s free plan only covers 2 projects.
Can I use time tracking for tax deductions?
Yes, many freelancers use time logs as supporting documentation for home office deductions and business expense allocation. Harvest and Toggl both export detailed reports that accountants can work with. Check with your tax advisor for specific requirements in your country.
