Themes from qualitative analysis of focus groups and usability testing.

Stage, position, theme			Representative quote
App development
	Patients
		Present treatment options in the app	“Present different treatment options, main risks of things, like with Chantix it is a plus and minus because it is actually very good at helping some people but it can have some nasty side effects.”
		Present cost in the app	“There was a cigarette calculator thing that I went online and you put in how many years you have smoked and how much and with that you could have bought a luxury car with all that money. Something along those lines.”
	Physicians
		Gauging their readiness	“I do not necessarily go through the formal stage criteria but after 20 years you have some idea of what phase someone is in. That helps to see if they are ready to quit-something like that.”
		Time to complete the app information	“If you are delaying my visit because they are out there filling this thing out and we are calling them and they are not done with their survey, then it would be a problem. Has to be done in waiting room or exam room before I get there.”
	Registered nurses and medical assistants
		What has worked in the past and what has not would be helpful	“I say the doctor has lots of materials and I ask them what they have been trying to do, what worked and what did not, it would be helpful to know that about the patient.”
App Testing
	Patients
		(Va1.0) Visual and ease-of-use	“More uniform text style, better contrast, too dark of a background, visually challenging-just kind of drives me crazy, lots of mental gymnastics that make you leap back and forth.”
		(V2.1) Customized feedback and knowledge	“I could tell that the feedback was customized at the end, kind of surprised, and I liked increased knowledge about cost of smoking and personal barriers to quitting.”
	Physician
		(V2.3.1) Evidence based methods	“Evidence-based methods are helpful, pros and cons, cost is helpful.”
		(V2.3.1) Saves time for visits about smoking or patient wants to discuss smoking	“Cuts back on me asking all the questions, gives you some tools that might be helpful, and app is a conversation starter.”
	Medical assistant
		(V2.3.1) Time for filling out app	“It was not disruptive, It went well and we still stayed on schedule.”
