Clockbook is the only 100% free time tracking app for Windows that lets you and your team log hours straight from your desktop while working.
Clockbook is a web-based time tracker and Mac-compatible time tracking software. It’s the only time tracking program that’s truly free, no matter how many projects you have or how big your team is.
Clockbook is primarily a browser app, but you can also install it on your Mac OS X as a native desktop app to make time tracking more convenient.
You can track how many hours you spend working on tasks from the Mac application, and then run reports, manage projects, and review timesheets in the browser version.
When you start working, just click the button to start the timer. You can also continue timer for some previous activity.
You can enter what you worked on and add a project, task, tag, and choose if it's billable.
Forgot to start the timer? Switch to manual mode and add how much time you've worked manually.
Clockbook can track what apps and websites you use so you can later create time entries based on time spent in other apps (data is visible only to you).
In the web version, you can manage projects, invite team, review timesheets, and export reports.
