The App.

About Change One Thing.

Service users, carers, and clinicians were involved in the development of the Change One Thing app.


The app is designed to be used as part of the DIAMONDS intervention to support diabetes self-management for people with severe mental illness.

User Guides.

Where can I find my PIN?

If you are a DIAMONDS Coach, a participant in the study, or are helping with testing the app, you will need your unique PIN to log into Change One Thing. 

If you don't have a PIN, please contact us.

Download Instructions.

Once you have your unique PIN and are ready to start, you can access instructions for downloading the app and setting up your profile here.

Please note, these instructions have been written using an iPhone but the process is very similar on Android phones.
