FreeCBT is a companion and self-help app designed for Cognitive Behavioral Therapy (CBT), which is widely recognized as one of the most effective treatments for depression, anxiety, and panic. Developed by Evan Rosson, this open source thought diary app provides users with a practical tool to identify and challenge automatic negative thoughts.

The app follows the popular three-column technique, also known as "catch it, check it, change it." By recording automatic thoughts, users can analyze and challenge them using cognitive distortions. This process helps individuals develop alternative thoughts, ultimately leading to a change in their emotions and behaviors.

FreeCBT is a user-friendly app that guides users through the CBT process. The interface is intuitive and easy to navigate, making it accessible to individuals seeking self-help or as a companion to therapy. As an open source project under the GPL license, FreeCBT encourages community contributions and provides transparency in its development.
