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.

What’s New

Version 5.1.6

In response to user feedback, the streaks functionality has now been updated to allow for new users to change the start date of their streak within the app, to accommodate for streaks that began prior to downloading the app.

New users who would like to edit their streak start date to a date in the past can tap the pencil icon next to “Streak started on…” in the My Streaks section. This allows the user to select a different date for their streak to begin counting from. Please note: this functionality is only available to users who haven’t yet ended their first streak in the app.

Additionally, in line with our policy to review the signposts within the app every 3 months to ensure all information is correct and up to date, minor edits have been made to some of the signposts.

Can't rate this app highly enough

This is the only app of its kind where I've genuinely felt a difference. So grateful that it's not filled with ads, in-app purchases and subscription fees like so many others; having said that I would happily pay a one off fee to support this app. It's really helpful to have grounding techniques written out in front of you as I struggle to remember any when I need them the most. Highly recommend this app to anyone dealing with impulsive thoughts or urges.

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)

P.S Love the app!!!!

Developer Response ,

Hi Leif, thank you for your lovely review! We're so glad to hear that you like the app, and we really appreciate your suggestions - I've logged them all for future review with our team. Have you found the Streak Awards section within My Streaks? This gives you awards for achieving various lengths of streaks, e.g. 3 days, 1 week, etc. which sounds similar to what you've suggested - although the accompanying messages that you've suggested sound great and I've logged those for review! Thanks again.

I’m so happy!!

I am so grateful that such an amazing app was created by such thoughtful people. It is the sweetest, nicest and most incredible idea and app I’ve ever downloaded. I think it works well and it honestly warms me up inside to know that apps like this exist. I am definitely going to raise awareness of this app, especially towards friends I know who are struggling with mental illness and more specifically, self harm. Thank you for creating this app. 💓
