Time Tracking Apps: 7 Best Picks for Hourly Billing
If you bill clients by the hour, every unlogged minute is money left on the table. That’s exactly why time tracking apps have become essential software for freelancers, consultants, and remote employees who need airtight records of their work. Whether you’re juggling five clients or reporting hours to a single employer, the right tool turns guesswork into precise, defensible invoices.
Remote work has made accurate time logging more important than ever. When you’re not sitting in an office where someone can glance over and see you’re working, your billing records become your proof of effort. A good app doesn’t just tally hours; it builds trust with clients, protects you during disputes, and gives you data to price your services more intelligently over time. If you want to dig deeper, our guide on Best Free Productivity Apps for Remote Workers covers this in more detail.
Why Time Tracking Apps Matter for Hourly Billing
Manual timesheets are prone to rounding errors, forgotten entries, and the awkward guessing game of “how long did that actually take?” Time tracking apps solve this by running quietly in the background, capturing start and stop times, and organizing everything into clean reports you can hand straight to a client or accountant. For remote workers who bill by the hour, this isn’t a luxury feature; it’s the backbone of getting paid accurately and on time.
Beyond billing accuracy, these tools double as productivity tools. Many freelancers discover, once they start tracking, that certain tasks eat up far more time than they assumed. That insight alone can justify raising your rates or restructuring how you scope projects. According to background on time tracking software, the category has grown well beyond simple stopwatches into full platforms covering invoicing, reporting, and team management.
The 7 Best Time Tracking Apps for Remote Workers
1. Toggl Track
Toggl Track is often the first name that comes up when freelancers discuss time tracking apps, and for good reason. Its interface is famously simple: one big button starts and stops the clock, and everything else stays out of your way. It offers a generous free tier for solo users, along with paid plans that add project templates, billable rate settings, and detailed exportable reports. If you want something you can learn in five minutes and never think about again, this is a strong starting point. You can explore its features directly on the Toggl Track website.
2. Harvest
Harvest leans heavily into the billing side of things, which makes it a favorite among consultants and small agencies. It tracks hours, then turns them into professional invoices without requiring you to jump between separate apps. It also integrates with popular accounting software, so your hourly billing data flows straight into your bookkeeping. The visual timesheets and expense tracking make it easy to see, at a glance, whether a project is running over budget before it becomes a problem. This connects closely with another common issue — see How to Use Time-Blocking Apps to Stay on Track for more on that.
3. Clockify
Clockify stands out as one of the few genuinely free time tracking apps with no cap on users or projects, which makes it appealing for freelancers on a tight budget or small remote teams just getting started. Despite being free, it still offers timesheets, reports, and a browser extension that tracks time spent in specific apps and websites. Paid tiers add features like invoicing and administrative controls, but many solo workers never need to upgrade. More details are available on the Clockify website.
4. Hubstaff
Hubstaff is built for remote teams where a manager or client wants more visibility into how hours are spent. It includes optional screenshots, activity levels, and GPS tracking for field workers, alongside standard time logs. Some freelancers find this level of monitoring intrusive, but for those working with clients who specifically request proof of active work, it removes any doubt about billed hours. It also supports automatic payroll calculations based on tracked time, which is handy if you manage subcontractors.
5. RescueTime
RescueTime takes a different approach by tracking time automatically in the background rather than requiring manual start-and-stop actions. It categorizes your activity across apps and websites, then generates reports showing how much of your day was genuinely productive versus distracted. While it’s less focused on generating client invoices, remote workers who bill by the hour often use it alongside a dedicated billing app to understand their real work patterns and cut down on time-wasting habits.
6. Timely
Timely uses AI to automatically record your work as you move through different tasks, then lets you review and confirm entries rather than typing everything in manually. This appeals to people who find traditional timers annoying to remember. It’s particularly useful for those working on many small tasks throughout the day, since it captures the details without demanding constant attention. The trade-off is a higher price point compared to some of the free or low-cost alternatives on this list.

7. FreshBooks Time Tracking
FreshBooks began as accounting software and folded time tracking directly into its invoicing and expense platform. For freelancers who want one tool that handles hours, invoices, payment reminders, and basic bookkeeping together, this integration saves a lot of back-and-forth between separate apps. It’s especially well suited to independent contractors managing several ongoing clients who need to bill by the hour on a recurring monthly basis, without juggling spreadsheets on the side.
Comparing the Top Time Tracking Apps
Choosing between these options often comes down to your budget, your need for client-facing invoicing, and how much automation you actually want. The table below summarizes the core strengths of each pick to help you narrow things down quickly.
| App | Best For | Free Plan | Standout Feature |
|---|---|---|---|
| Toggl Track | Simplicity and ease of use | Yes | One-click timer |
| Harvest | Invoicing and agencies | Limited | Built-in billing |
| Clockify | Budget-conscious freelancers | Yes, unlimited | Free for unlimited users |
| Hubstaff | Client oversight and remote teams | Limited | Activity monitoring |
| RescueTime | Productivity insights | Limited | Automatic background tracking |
| Timely | Hands-off, AI-based logging | No | AI-generated timesheets |
| FreshBooks | Combined billing and accounting | Trial only | All-in-one invoicing suite |
How to Choose the Right App for Your Workflow
Start by asking what actually frustrates you about your current billing process. If invoicing is the pain point, Harvest or FreshBooks will likely save you the most time. If you simply need something reliable and free for freelance time tracking, Clockify is hard to beat. Remote workers managing subcontractors or needing proof of active hours might lean toward Hubstaff, while anyone who forgets to hit “start” constantly should look at automatic options like RescueTime or Timely.
It also helps to trial two apps side by side for a week before committing. Most of these tools offer free tiers or trials specifically so you can test them against a real project. Pay attention to how the mobile app performs, since remote workers often bill hours from different locations and devices throughout the day, not just from a desktop. A tool that feels clunky on your phone will eventually get skipped, and skipped entries defeat the entire purpose of tracking in the first place.

Ultimately, the best time tracking apps are the ones you’ll actually use consistently. A feature-packed platform means nothing if it sits unopened while you scribble hours on a sticky note. Pick something simple enough to become a habit, accurate enough to defend your invoices, and flexible enough to grow as your client list expands. For anyone serious about hourly billing, that consistency is worth more than any single fancy feature.

Clockify is widely considered one of the strongest free options, offering unlimited tracking, projects, and users without a paid subscription, which makes it especially attractive for new freelancers testing out hourly billing for the first time.
