• Name: List of mental health apps.
• What is it? 
  • Mental health apps from a systematic review, research papers and pilot studies.
• Why do you like it? 
  • I have not tried these. But they seem to be promising because of the research behind them.
• Where to start?

The list of the most promising apps against mental illness according to a systematic review (Miralles et al., 2020):

• Actissist and UCSF PRIME reduced psychotic symptoms and symptoms of schizophrenia.
• Virtual Hope Box reduced self-harming and suicidal behaviour.
• Agoraphobia free reduced symptoms of agoraphobia.
• Challenger reduced general anxiety and social anxiety.
• MoodHacker and SuperBetter reduce depression.
• SuperBetter increased pain management and reduced depression (d= 1.05) (Roepke et al., 2015; Devan et al., 2019; Miralles et al., 2020).
• PTSD Coach reduced PTSD symptoms (d= .41), depressive symptoms (d= .45) and increased psychosocial functioning (d= .51) (Kuhn et al., 2017).

Some additional apps are listed here:

• Mindease reduced anxiety. A pilot study showed a 51 % reduction in anxiety (Brietbart, 2018). 
• Happify increased positive mood with 27 % and well-being with 11 % during a 8 week trial and it had a dose-response relationship (Carpenter et al., 2016; Parks et al., 2018).
• TeleCoach reduced hazardous alcohol use (d= 1.37) (Berman et al., 2020). 
• ‘Calm’ and ‘Headspace use mindfulness and guided meditation. Headspace reduced anxiety and depression. It also increased positive affect and well-being (Bostock et al., 2019; Wang et al., 2020).
• ‘CBTi Coach’ and Moodmission uses CBT principles and techniques (Wang et al., 2020).
• Additional evidence-based apps against mental illness can be found at the United Kingdom National Health Service: https://www.nhs.uk/apps-library/category/mental-health/ 
• There are many systematic reviews, meta-analyses and other research that look at more apps. It would be good to do an overview over the evidence and accessability in the field of mental health apps.
