The iPad version has a well-designed and pleasing interface. Food intake can be recorded manually or via barcode.
Calories burned during exercise are integrated into the allowance for daily eating. The app tracks not only calorie intake, but also protein, carbohydrate, fat, and sugar intake. This level of detail is more difficult to find among the available apps in this category. Fiber intake "accounting" would be an excellent feature for future upgrades to this app. The app features community integration and sharing for users who desire such features. One flaw of note is that if a user makes any changes to their initial profile in the app, they must reselect their weekly weight loss goal. If they do not do this, the daily calorie limit will be incorrect.
Overall Impressions from Around the Web:
Positive reviews with well over 200,000 downloads. Users seem very happy with the performance as well as the price. Many apps are not as well-supported or too high-priced and will presumably fall by the wayside as the app market matures but this is probably not one of them.
