Positive comments
Easier to figure out and use than most apps	App was very user friendly!
I liked it because you could track how you drink and your BAC	Loved the layout, self-explanatory tabs
	Easy to learn
Easy to navigate with the categories on the left side	I often played with the app throughout the day
Foolproof	Entertaining, not bland
Self-explanatory	Not a hassle to use every day
Some were really cool and I had no idea those were myths or real [about the texts]	Liked how the Coach was never negative; it was always positive
The calculator was so cool—could lead to fewer accidents and more understanding of BAC and timing of drinking	Informative, very in-depth information
These strategies raised my awareness and I noticed which strategies do correlate with drinking less	I did have fun with the trivia…pulled out the trivia game with my friends; it was a learning experience, even with them
I think that you could help a lot of students	Good facts in the trivia game; I learned a lot
I liked that you could customize them—weight gender, type of drink, timing [about BAC calculator]	I liked the quotes—They were unexpected
I think it’s beneficial because it’s not in your face, like “your drinking habits are bad”	I planned on using it 10–15 min every night, but I ended up using it more often when I was bored
It helps you help yourself
Negative comments
Would like to be able to add drinks at a later date	Sometimes I missed the messages because they were coming in fast The appearance was a little too bright
Overwhelming at first—It didn’t stop. I like to get rid of my notifications [about the texts]
Too many topics back to back in a short period of time	I would like larger text size

Note. BAC = blood alcohol content.
