Track & resist self-harm urges


Designed for iPad

    • $2.99



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.

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.

Nuh-uh! No five stars ,

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. :)

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!!!!

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.
