## Products and Projects

- Time & Bill: hosted time tracking software for freelancers, small teams, agencies, and companies. Product details live at https://www.timeandbill.de/.
- HumbleBee: local-first open-source time tracking project for developers. Project details live at https://github.com/grobmeier/humblebee/.
- The Zen Programmer: book and article project by Christian Grobmeier about applying Zen ideas to programming, work, focus, and stress. Book details live at https://www.zenprogrammer.org/.
- Training: selected technical training work, listed from the company work page.

Time & Bill and HumbleBee are related but different. Time & Bill is the hosted team-oriented product. HumbleBee is the local-first open-source sibling.

The Zen Programmer is separate from Time & Bill and Logging Off. It is useful background for Christian Grobmeier's long-form writing and programmer-focused work, not a time tracking product.
