BlueIce is a self-help app to be used as part of an intervention for young people who self-harm. It was co-designed with young people and is informed by cognitive behaviour therapy (CBT) and dialectical behaviour therapy (DBT).

BlueIce includes a mood monitoring diary and a personalised self-help menu of mood lifting activities, including music and photo libraries, physical activities, audio-taped relaxation and mindfulness exercises, identification and challenging of negative thoughts, and distress tolerance activities.

After use, young people are asked to re-rate their mood and are routed to emergency numbers if they are still feeling an urge to self-harm.
