The investigators aim to enroll 120 youth (30/site) 13-20 years old who report regular access to an Apple or Android smartphone. Following completion of a baseline survey, participants will be individually randomized at a 1:1 ratio to 1 of 2 smartphone app conditions: (1) Bodhi AIM (Action In Mindfulness), a 30-day meditation app or (2) HIB (Health In Balance), a health promotion control app matched to Bodhi AIM for time and structure. Follow-up assessments will occur at 1 and 6 months. All study activities will be remote.
