Description from the app store — not vetted by MIND
The urge to self-harm is like a wave. It feels the most powerful when you start wanting to do it.
Join over 2 million users and learn to ride the wave with the free Calm Harm app by choosing activities from these categories: Comfort, Distract, Express Yourself, Release, and Random.
There is also a breathing technique to help be mindful and stay in the moment, regulate difficult emotions and reduce tension.
When you ride the wave, the urge to self-harm will fade.
Calm Harm is an award-winning app developed for teenage mental health charity stem4 by Clinical Psychologist Dr. Nihara Krause, in collaboration with young people, using principles from the evidence-based Dialectical Behaviour Therapy (DBT). It is built to NHS standards and approved by ORCHA.
Calm Harm provides some immediate techniques to help break the cycle of self-harm behaviours and explore underlying trigger factors; build a ‘safety net’ of helpful thoughts, behaviours and access to supportive people; and provides the opportunity to journal and self-reflect. It also provides signposts to help.
The Calm Harm app is private, anonymous and safe.
