Meet Rejoyn

A new approach in a changing world

Rejoyn is an easy-to-use smartphone app developed to support people with depression. Rejoyn can be used alongside your usual treatment to help reduce symptoms of depressive disorder.

How does Rejoyn work?

Like physiotherapy for your brain

Over the course of 6 weeks, Rejoyn treats depression symptoms with clinically tested brain exercises and short, skills-based therapeutic lessons.

Information on the intended use of Rejoyn and how to report side effects can be found at the bottom of this page.

Brain exercises

3X PER WEEK

APPROXIMATELY 15-30 minutes each

  • The brain exercises in Rejoyn involve identifying and remembering emotions on a series of faces
  • These exercises are designed to strengthen the connections between the feeling and thinking parts of the brain, improving how they work together to process emotions, which may help to reduce symptoms
  • Repetition of these exercises is important to help strengthen these connections
  • The exercises are designed to keep patient's brain challenged and engaged

Therapeutic lessons

3X PER WEEK

APPROXIMATELY 5 MINUTES EACH

  • Therapeutic lessons teach patients skills that can help with managing depression symptoms, including handling strong emotions, reframing negative thinking and taking positive actions
  • After the 6 weeks are complete, patients will be able to access the therapeutic lessons for an additional 4 weeks

Text messages and in-app notifications

  • Optional in-app reminders encourage patients to complete exercises and help to reinforce learnings from the therapeutic lessons
  • Building a routine may help to make it easier to stay on top of treatment

'Rejoyn represents an innovative convergence of novel neuroscience and accessible technology, backed by clinical evidence. Rejoyn's brain exercises were lab-tested and combined with therapeutic lessons that were written by a team of licensed psychotherapists.

We are excited to bring this new therapeutic option to patients in Great Britain with depressive disorder episodes'.

Daniel Carpenter, PhD, Senior Director, Global DTx Product Development
