Calm Harm provides tasks to help you resist or manage the urge to self-harm. If you want to you can set a password so that it's completely private. You can also personalise it if you wish, by choosing the background colour theme and deciding on whether you would like some company using a variety of friendly characters.

The app then provides you with four categories of tasks to help you surf the urge. ‘Distract' helps in learning self-control; ‘Comfort' helps you care rather than harm; 'Express Yourself' gets those feelings out in a different way and ‘Release' provides safe alternatives to self-injury. There is also a ‘Breathe' category to help calm and get back in control.

You can do the activities for either blocks of five minutes or fifteen minutes with a countdown for each minute. You will be able to track your progress and notice change*.

Calm Harm has been developed for teenage mental health charity stem4 by Dr Krause, Consultant Clinical Psychologist using the basic principles of an evidence based treatment called Dialectic Behaviour Therapy (DBT).

Note that if you forget both your password and memorable word, these cannot be reset as we do not create user accounts, and you will need to re-install the app, losing any previous data.

*Please note the app is an aid in treatment but does not replace it.

Good App, some suggestions!

I saw this app on Twitter. I was looking for an alternative to some breathing based apps for winding down and then saw the distraction option for this app (and the breathing one). Thought it was an interesting concept even though I don’t physically self harm (I just overthink things). I know this is geared towards people who self harm but really it could be used for everyone at every age. I think it’d be helpful if you had different reasons to choose from why you’re using the app because the get help literature is excessive upon first use and kind of put me off a little bit. Also, it was giving an error when selecting location so I picked a different location and changed it later in settings. When people want help the last thing they need is an error screen. Otherwise, great app upon first use. Will return and hope for positive changes!

This app has literally saved my life

This is a wonderful concept. I think my favorite part about it is that the activities have categories. For instance, very few health apps have a “distract” solution. This is often one of the most important ways to help someone in the moment. Thank you for being absolute geniuses. The customization within the app is also very soothing, and the little characters are adorable. Science says that living by a body of water is good for the mind, so your theme is sweet and reminds me of the ocean and every wonderful memory I have from going to beaches. If there is any way in which I can support your app, I would love to. I do recommend that you take a page to list hotlines, not your own, but maybe the national hotlines for most countries. I don’t know what permissions are involved with that, but I feel like that would be the only touch that could make this even better than it already is.

Amazing but has some flaws

It’s annoying to constantly have to log back into it. I don’t know if it’s just me or other people are having the same problem. Sometimes I forgot my password and memorial word and can’t get in for a while. I get it that it can be tracking you for improvements or something, but I think it should be something that you can just jump right into whenever you need it. Other than that though, it’s amazing and I really recommend it anyone who’s struggling with self harm or any other mental illness. It’s not given enough credit for the fact that it can also help with panic attacks, depressive episodes, bursts of anger, and simply something to keep you calm.
