Catch It is a joint project between the Universities of Liverpool and Manchester, to help users better understand their moods through use of an ongoing diary.

The app was designed to illustrate some of the key principles of psychological approaches to mental health and well-being, and specifically Cognitive Behavioural Therapy (CBT).

It is not intended to be a substitute for professional mental health care, therapy or advice. If you are worried about any aspects of your mental health, you should approach a professional.

Share function doesn’t work

I wanted to be able to print/email my diary but that function doesn’t work - it just freezes.

I personally feel like this app will help anyone who suffers from anxiety/depression or even if you’re an overthinker like myself. Because I won’t talk to people about my emotions, this app allows me to get it off my chest in a viewable format instead where I can see my past emotions, log it and learn from it. The first time I used this, straight afterwards I felt so much better and no one had to know I was upset apart from me!

Love it.

I have anxiety, depression and PTSD from emotional abuse. This app is literally the best thing ever. I’m new to CBT and have been told to journal by a counsellor. This allows me to record all my anxiety, irritability, PTSD episodes, and depressive periods as well as write the situation, negative thoughts, and turn these into positive thoughts. It really calms me down and soothes my mental state. Only thing I’ve noticed is the “share diary” doesn’t work.
