FreeCBT is a self-help app that can be used by anyone who needs to improve their mental health and is suitable for people of any age. It is an open-source thought diary for cognitive behavioral therapy (CBT).

CBT is a type of psychotherapy that can help people who have a mental health problem. It can also be helpful for people who just want to improve their mood and cognitive abilities. The way it works is by helping people identify the thoughts and feelings that they have, along with how it makes them feel. Once they have identified the thoughts and feelings that they have, they will be able to change the way they think and feel.
