This app ignores the exercise angle and only summarizes food data in terms of calories. It does, however, show your daily calorie count in the lower-left corner and superimposed over the app icon on the iPhone home screen.

This app's strength is that it pushes the meal and planning angle, even so far as to incorporating a shopping list into the app.

The Bad: The food database seems to be lacking. None of the results for a search on "bread" seems to actually yield any bread.

This is the home screen of the app, showing the "meals" and "foods" that have been consumed today. Note that a meal is composed of individual foods. The calorie count for the day is shown in the lower-left corner. The "add to shopping list" option gives a short list of the foods that were consumed today, which seems an odd way to do things unless it is assumed that the user is going to a previous day in order to buy ingredients to have the same meal in the future.

This is the meal screen -- in this case the screen was reached from the "add meal" button, so clicking on the meal adds the meal to the current day's journal. If the screen is reached from the menu button, then clicking on it provides a more detailed view of the meal.

This is the more detailed meal viewing/editing screen.

The search screen.

The shopping list. Items can either be checked off or added from this screen. Note that the items give very poor quantity information.

This is the foods screen, which can either be reached using the "Add Food" button from the journal screen or the Food menu icon. This list seems to function as a user history of the subset of foods possible. Also, custom foods can be created off of this screen by entering in nutritional information.
