Headspace

Founded by former Buddhist monk Andy Puddicombe, Headspace has more published peer-reviewed research than any other meditation app — over 70 studies. Research shows it reduces stress by 14% in 10 days, improves focus by 14%, and reduces aggression by 57%. It was the first mental health app prescribed by the NHS in the UK. The guided meditations are genuinely well-designed, and the animations explaining mindfulness concepts are better than most therapy explanations.
