How to Navigate
“Calorie Abacus” has four main navigation features, designed to make browsing through the application fast and easy.
1. Navigation Bar always contains a shortcut to the Main Menu and any other buttons applicable to the currently displayed screen.
2. Flip through categories. Swipe your finger left or right to browse through the 5 food categories the same way you flip through pages in a book.
3. Scrollable list. Each food category contains a list of items sorted in alphabetical order. Use your finger to scroll up or down the list.
4. Sub-category shortcuts. Each of the 5 food categories is divided into 2 sub-categories. For example, “Fruits and Vegetables” group is divided into “Fruits” and “Vegetables”. Simply tap on the sub-category name to go the beginning of the sub-category list.
