What athletes and coaches are saying
“You all should try Stans app while you have a chance. It’s super cool. You don’t have to count your macros or log anything. Just take a picture and his app calculates it all. It’s pretty amazing!!”
“This is so cool! I’m often really busy and like most people grab something quick, but the quick choices aren’t always the best. Although I don’t need to lose weight, I have to maintain and I think something like this would be helpful as meal timing before the hard workouts each week is a challenge since I’m up at 4:30 on Tuesdays, can’t eat for an hour but have to leave and teach a class before the binge workout.”
