First what I love is I dont need to have the latest apple software installed to utilize this app. There are lots of peeps with old iPhones and it is just not possible to get iOS 7. Now let me get to what makes the app operation so great. You can track not only your points but calories, fat, protein, sodium, carbs and more to fine tune what mix of these elements affect your progress or lack thereof in losing weight. This app is worth the cost! Buy it, youll love it:)
