The app is amazing since it helps you to monitor your food intake and lose weight without following an extreme diet rather a life style. However, the sync between myfitnesspal and my Fitbit app is usually not accurate so I depend on my Fitbit to see how many calories were in and out. In myfitnesspal sometimes it shows that it is sync and sometimes I get a value of 0 although I exercise 5 days a week.
