Eligible participants used opioids and injected drugs within the past week. Participants received a smartphone, unlimited data plan, and e-harm reduction focused mHealth application based on the self-determination theory principles of autonomy, competence, and relatedness. The app was used to deliver a 12-week overdose risk reduction intervention. Every week, participants self-selected 1 of 11 available overdose-focused harm reduction goals and received tailored education, resources, and support from study staff through the smartphone application. We evaluated the use of app features, intervention adherence, and described the most commonly selected overdose risk reduction goals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Of available app features, participants most often used private messaging (median, interquartile range [IQR] days used: 28 [18-53]), viewed a motivational \u201cthought of the day\u201d (median [IQR] days used: 24 [15-47]), and interacted with discussion boards (median [IQR] days used: 12 [5-24]).
