Perceived benefits
	Usefulness
		Evaluate health conditions and health literacy before surgery	“Well, yes it’s a good app, because it’s got a lot of benefits; our progress, our goals, resources we can use, so, yes, it’s probably good for everybody here.” [group 1-05, female]
		Access to health-related knowledge, skills, and referrals	“Looking at the resources that they’ve offered, it’s a personal lifestyle app.” [group 2-05, male]
		Improving the patients’ motivation	“If it’s just going to be a tool for yourself, perhaps an inspirational tool?” [group 1-01, male]
	Ease of use
		Easy to use the system	“Yes, I think it’s good, it’s quite easy to follow, because I’m not very good at this, but I found it quite easy.” [group 1-02, female]
Improvement
	Survey
		Inflexibility	“I physically cannot walk ten minutes, so my answer to the question is zero, but when I tried to complete the page, it’s telling me it’s incomplete, so all the information I put in is going to be junked (deleted).” [group 2-03, female]
		Ambiguity	“Click on what? No, something’s wrong.” [group 1-02, female]
	My Goals
		Insufficient feature	“When you complete the survey at the start about you, yes, you’ve got a baseline, but over a period of time, the app is not collecting anything.” [group 2-02, male]
		Suboptimal interface design	“What about a graph about filling out or achieving the goals and seeing...something visual.” [group 1-05, female]
		Lack of tracking	“...is there a place where you can monitor your weight loss as you go?” [group 1-06, female]
	My Resources
		Insufficient information and referrals	“...it does need more resources in it” [group 2-02, male]
	Push notifications
		Personalization	“Maybe there’s an option that you can turn that setting on or off...So, I like to stipulate what time (messages arrive).” [group 1-06, female]
