Pin it or Bin it is an iPhone app designed by psychologists at the Universities of Liverpool and Manchester, along with students at Liverpool Life Sciences University Technical College. It aims to illustrate key principles of Cognitive Behavioural Therapy (CBT) for mental health and wellbeing. CBT focuses on how our thoughts impact our emotions and mental health. The app offers a simple approach to dealing with troubling memories, allowing users to 'pin' positive events and 'bin' negative memories to promote mental wellbeing.

The app encourages users to focus on positive memories by 'pinning' them, helping in remembering good times, and provides a structured way to move on from negative events by 'binning' them. By asking reflective questions, users can resolve issues and remind themselves to move forward. Pin it or Bin it emphasizes the importance of practice in improving mental health, offering a straightforward tool for those taking the first steps towards better mental wellbeing.
