Theme			Participants, n (%)		Example participant quotes
What features of the app do you use the most? Why?
	Check-ins and how am I?	20 (83)		“Probably just the check-ins like the news press and the daily check-ins. And why is because it is easy to use.” (Female, aged 46 years) “That it keeps track of how many days I’ve been opioid-free. It’s like a reminder.” (Male, aged 36 years)
	Community board	5 (21)		“The community board is awesome” (Female, aged 32 years) “...the community board. It’s not just reading the same questions every day.” (Male, aged 29 years)
	Messages and contacts	5 (21)		“I like the fact that I can also, you know, contact doctors on and you know, all the staff here you know. That’s pretty cool.” (Male, aged 29 years) “The thing I use the most probably is the contacts and talking to like [name] daily.” (Female, aged 32 years)
Is there anything that would make you want to use it more? What?
	More community activity	3 (13)		“More people participating in the community section would make me wanna use it more because there would be more people to interact with.” (Male, aged 36 years)
	Technical improvements	2 (8)		“The only thing that would make me want to use it more is if when I do the check-in, I could do mood, stress, and medication usage. If I could do everything all at one time as opposed to having to do mood and stress for one day and then having to do medication usage—and, the last question...” (Female, aged 46 years)
	Nothing	17 (71)		“I don’t think so. It was pretty set up pretty good.” (Female, aged 31 years)
How has the app changed your connection to your clinic, if at all? How has your use of the app affected how you and your provider communicate?
	Easier communication	12 (50)		“I’m able to get in touch with the clinical team a lot easier and ask questions any time of day or night” (Male, aged 32 years) “Instead of looking for a phone number, I can just email him right then and there. I don't have to Google, you know, just to try and find the office and then you just, you know, the physician whatever, so it’s just a lot easier to get in touch with each doctor.” (Male, aged 29 years)
	More direct communication	10 (42)		“It’s straight to the provider instead of having going to talk to other people first.” (Female, aged 31 years) “Instead of having to go the whole hospital there, I can just directly ask.” (Female, aged 31 years)
	More access to providers	9 (38)		“It helps the providers here know what’s going on with you, and if there’s something really bothering you or you—it’s an emergency you need to reach out to someone, they’re right there on the phone.” (Male, aged 38 years) “Me and [name] keep in touch, and just if I really need anybody to talk to, I can always just reach out to her easily.” (Female, aged 32 years)
	Quicker communication	8 (33)		“It makes me know that if need help, that I can get in contact and a little bit quicker.” (Female, aged 31 years)
What do you dislike about the app?
	Technical issues	4 (17)		“I don’t dislike it, but the only thing it does seem like request that there is a message and there is nothing there” (Female, aged 31 years)
	Repetitive	4 (17)		“the repetitiveness of the comments when you’re inputting your information.” (Female, aged 33 years) “It’s the same 3 questions, and most of the time my answers never change for the most part. There are always almost always the same unless something spectacular happens with my day, but other than that, it’s just the same questions, same answers.” (Male, aged 29 years)
	Nothing	13 (54)		“I don’t think there’s anything I dislike.” (Male, aged 60 years)
What are some ways that the app could be more helpful to you?
	More community activity	4 (17)		“Just other than more people should interact on the community section. Maybe you can do categories on the community section.” (Male, aged 36 years) “It’s nice when like people under the comment section do positive, kind of positive encouragement. Maybe there’s a way to, I don’t know how to encourage people to maybe daily or once weekly try to post a positive thing.” (Female, aged 33 years)
	Nothing	15 (63)		“Right now, it’s doing great for me.” (Female, aged 33 years) “I think it’s pretty good the way it is, the way I use it.” (Female, aged 31 years)
