What We Do
Our mission is to make mental health support available to everyone, everywhere. Tellmi is a multi-award-winning, fully moderated, anonymous, mental health service predominantly for young people aged 11-30. The Tellmi app safely enables young people to talk about difficult things and encourages them to help themselves by helping each other. Beneath an engaging anonymous peer-to-peer feed, Tellmi integrates the latest psychological research to promote the development of protective factors such as emotional resilience, empathy, social skills, stress management, and coping techniques. Tellmi is commissioned by the NHS and Local Authorities across the UK.
The Tellmi app is free to download with premium features in commissioned areas. The app is available 365 days a year, 24/7, and our moderators, counsellors, and therapists are available from 8:30 am until 11 pm every day. Tellmi’s specialist extensions currently offer support for autism, diabetes, and unemployment, with new areas being planned for 2026.
