Catch It

The University of Liverpool

About this app

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.

Ratings and reviews

This app used to be really helpful but the January 2025 update has changed what we are encouraged to reflect upon: instead of getting us to think about automatic thoughts it now shows us what we wrote in the "what was happening just before"-section. So it's just not working anymore.

I like that you could add a PIN to make sure only you can see it. It's quite a simple app, but I don't really like how the diary system works. I feel like just having "Happiness, Depression, Anger, Anxiety" are quite vague. Maybe the app would be better if you could add your own custom emotion? That'd be much better than just "other". I don't like the way selecting the date and time that emotion happened works. It could be a little simpler. Like selecting Morning, Night, Evening, etc.

Love that you can enter your own emotion descriptions. This is a brilliant way to implement CBT in an app form. I wish you can: (1) delete entries (I entered something incorrectly and can't remove/edit it now) and (2) completely exit when you "log out" of the app (currently you can use "back" to go through previously viewed pages, even though you're logged out)

What’s new

We're excited to bring you a major update with improved features and performance.

By choosing to share anonymous usage data, you can contribute to the University of Liverpool's mental health research. The app remains free to use even if you decide not to share your data.

Existing users can update the app without uninstalling the old version to keep previous diary entries. You then can choose any PIN.

We hope you enjoy the new version of Catch It!
