App features and impact			App usage	Interview quotes
Meal reminders
	Supportive
		Structuring	Continuous logging	“I feel like it [RR] is helping me quite a lot. When I started eating according to the meal plan, it was a good way to make sure that I was actually following the plan. I need that structure in my life in order to eat what I’m supposed to.”
	Obstructive
		Reminder of illness and treatment need	Avoiding to log or turning off feature	“Actually, the app is quite challenging. First, you have to eat. And when you've eaten, you have to log it. So you're reminded that you've eaten. Again. And you just wanna move on.”
		Condescending	Avoiding to log or turning off feature	“It's not like my problem is that I forget to eat, but that I sometimes don't want to.”
Affirmations
	Supportive
		Encouraging and rewarding	Continuous logging	“It’s affirmations like ‘I wanna be kind and loving to myself today’. It’s so basic, but then you think, I haven’t been kind to myself all day. Or maybe the entire week. And the more times you get those hints, the more they stick with you.”
	Obstructive
		Condescending	Avoiding to log	“It seems like it’s supposed to be fun logging all this stuff, but for me, it’s a serious thing that I need to get used to [logging]. It becomes too much fun and games.” “And it’s like ‘here’s a treat for you, since you’ve been good’. And that makes you feel less inclined to recover. It's a bit childish and condescending. When you have this [eating disorder], it's like you’re becoming a kid again, 'cause you can’t eat on your own. That's reinforced by the app treating you like a child.”
