Klokki Slim is fully ready for macOS 11 Big Sur. Give the simple but powerful time-tracking experience a go and share your experience with us.

Klokki Slim delivers a powerful and beautiful way of time-tracking directly from the Menu Bar. Focus on your work and enjoy an efficient way of tracking your time on projects.

Track your revenue by defining an hourly rate on folders and tasks. Manage your billable sessions by marking them as billed or paid, right from the reports window. Easily get back to and change the status of billed-out sessions from the convenient session inbox.

Link your favorite services and keep your time in sync. Jira is already ready to be synced with and more service will be added over time.

The most powerful and flexible reports will equip you with the possibility to access previously tracked time and filter it by date ranges or projects. Monitor how you worked within a week by checking the chart view or select multiple time-sessions and instantly see a summary.

The timer gets out of your way and always stays just a click away in the menubar. This way you can also have a quick glance to check how much time you already spent and not lose the focus.

Klokki Slim works everywhere. It doesn't matter if you are in an office or on an airplane. You will never lose a second just because there is no internet connection.

The folders and tasks structure provides a flexible way of organizing your projects. Choose from a set of colors to better fit the identity of your projects. Completed a project or task — archive it, without losing the time nor the ability to get back to it.

Don't worry about forgetting to pause the timer. Klokki Slim will notice if you are away and ask what it should do. You can adjust the absence period to better fit your workflow.

Keyboard shortcuts will improve your workflow and help to be even faster. Klokki Slim provides the possibility to set up your own shortcuts and have full control even without a mouse.

Klokki Slim is by default entirely private and doesn't send away any of your information. All your data belongs to you.

What’s New

Version 1.3.2

Hello awesome people! We were hard at work to ship another update that includes many things that will improve the overall experience with the app.


** Jira Ticket-ID **
From now on, when you sync your Jira tasks, the Ticket-ID is also going to be included in the task name.


→ A few Jira-server issues. The Jira-integration should now work a lot more reliable.
→ A bug that crashed the app when editing a running task from the reports sidebar.
→ Some app icon resolutions.
→ An unwanted activation of the timer when dragging the mini-tracker around within the menu bar.
→ The space between the task name and time.
→ Some UI issues on Mojave.
→ Other minor issues.

Please consider leaving a review, it's the only way others can learn about the app, and for us as indie-makers — it means the world. Thank you for supporting us!

So simple, just what you need

This is a very well done app. It is really easy to go crazy ini the time tracking space with lots of extras etc.

This app is super lightweight and has exactly what 99% of people are hoping for.

Really well done. Its hard to make things feel this simple.

Really simple and reliable.

This app is really simple, intuitive, and reliable.

I'd gladly pay for the ability to generate invoices to PDF and sync across devices, but other than that, this app is about everything a freelancer needs.

Thank you for sharing your feedback with us.

Just What I needed

I needed an app to track how long I work on retouching for different clients. I can easily start and stop, and switch between clients on the fly. It does everything that I needed. The reporting with graphs is a nice touch.
