Participants’ perceptions of the mHealth app and representative quotes.

Participant perceptions	Representative quotes
Encouraged reflection on factors that influence health	“[The App] helps me think about how I can use [my family] to support me...even though they live far away, I can just have a conversation with them and try to use them as part of my support, as well as my community, which are my friends, my church, my school parents, things like that. ’Cause I realize that these are actually part of the environment that could help me be a healthier person.” (App-only) “It makes me decompress from my day and just think, “How could I have made my day better? What did I do? What didn’t I do?” (App-plus)
Supported healthy behaviors	“I was more conscious of what I ate. I started...drinking more water, less caffeinated beverages, less carbonated beverages...I wasn’t as tired. I set a goal where I was going to bed by a certain time.” (App-only) “When I go see my doctor, it’s kind of like, ‘...you need to exercise more...you need to change your diet’. But the nice thing about [the app] was [it] broke it down into these things that you could learn about that allowed you to have a better understanding [of] your health condition...and also how you can sort of prevent certain health risks from happening.” (App-only)
Daily use was burdensome	“There [were] a lot of questions about how I feel today...it just seemed to be a little bit of the same old same old every day or every time I looked at it.” (App-only) “[The App] just got too time consuming and I just lost interest in keeping track of all that data. It just became too overwhelming, I was doing other things.” (App-plus)
Failed to consider personal circumstances	“I [have] paroxysmal afib, which means some days...I didn’t feel very energetic...[But] there was no way to [tell the app], ‘this day is different for completely non-purpose related reasons’.” (App-plus) “Sometimes [things] go completely awry and just change what’s gonna happen, my plan for the day. So outside factors...absolutely [have] an impact on your day. So you can still be positive, you can still have a plan for exercise. But sometimes, there’s things that come up...” (App-plus)
