Description

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.

This app helped me so much. I got a new personal best! I haven't self harmed in over a month and it's because of this app. no matter what's stressing you out this app will help. there are so many activities to do based off of what will help you, for example two categories would be comfort and distract but there's so much more. one of the activities is literally : lie on the floor in the dark and listen to music. that's my favourite one. this app is the most amazing thing I've ever found

Amazing app, beneficial for all 🤍🩷

I have found this app very helpful not only for myself but for friends of mine that have needed help with managing sh urges. It was reccomended to me by an online helpline during times of struggle and have since had the app for about 2.5 to 3 years and have found it very beneficial 🤍

Awesome!! Also have a suggestion :)

I haven’t been using this app for not a long time and my therapist recommended it to me, but I absolutely love it already, all the activities and breathing exercises are lovely and its helped urges a lot !! I do have a suggestion for a dark mode option, as there are themes but the screen is bright. I use it at night as well and its super harsh on my eyes haha! Of course you don’t have to add it, it would just be great. :) Thanks!<3

Suggestion…

My favourite app ever made so far, but I have a suggestion, my suggestion is that maybe every day you get a star sticker! And the star sticker come with a message like “Say ‘I am beautiful’ 10 times” or something, And when you stay on for a week long streak you get 3 star stickers! And maybe a dark mode is introduced? (Just suggestions, you don’t have to add them) -Leif 🤍 P.S Love the app!!!!

The reason for a password

The reason this app has a password is because many people don’t want other people in their privacy and that is what a password is for it is used to keep things private so that not everyone has to know.
