The main questions it aims to answer are: In American Indian/Alaska Native communities with unique cultural characteristics, how should a youth-focused sociotechnical behavioral health intervention be designed to encourage sustained engagement and positively impact indicators of behavioral health?; How can interactive technical interventions be designed to best support sustained community engagement in a challenged network environment? Participants will: * Receive daily guidance and encouragement to use the app from an anonymous, trained peer mentor * Be able to ask their peer mentors questions in a monitored one-on-one chat in the QI app or in a monitored group chat in the QI app * Log their mood and stress level on the app once per day * Practice mindfulness skills as directed in the QI app, including guided breathing, meditation, drawing, coloring, and walking * Practice Hopi cultural activities like running using the QI app to help track progress towards team mileage goals
