# Calorie Counter
|
||||
|
||||
**Tier:** 3-Advanced
|
||||
|
||||
Getting and staying healthy requires a combination of mental balance,
|
||||
exercise, and nutrition. The goal of the Calorie Counter app is to help the
|
||||
user address nutritional needs by counting calories for various foods.
|
||||
|
||||
This app provides the number of calories based on the result of a user search
|
||||
for a type of food. The U.S. Department of Agriculture MyPyramid Food Raw Data
|
||||
will be searched to determine the calorie values.
|
||||
|
||||
Calorie Counter also provides you, the developer, with experience in transforming
|
||||
raw data into a format that will make it easier to search. In this case, the
|
||||
MyPyramid Food Raw Data file, which is an MS Excel spreadsheet, must be
|
||||
downloaded and transformed into a JSON file that will be easier to load and
|
||||
search at runtime (hint: take a look at the CSV file format).
|
||||
|
||||
## User Stories
