Calorie Calculator

Overview

Calorie Calculator is a web app that allows users to keep track of their food intake and expenses, aided by a calculation of their current Basal Metabolic Rate and number of calories needed to maintain, lose, or gain weight. This app is a useful tool for those who are aiming to cut or maintain weight, gain muscle, or to manage their expenses.

Each registered user owns their own food catalog and will have the ability to set caloric and monetary goals for each day. As the day goes by, the user can add foods they have eaten to their catalog. The user will be prompted to enter the name of the food, the time it was consumed, the price, and most importantly, the total calories. As the user continues to add new items, the app notifies the user when they have reached the midpoint of their goals and when they have surpassed them. The user will be able to moderate their choices via a counter that displays how many calories they have eaten as well as another one that displays their total amount of money spent.

For each day a user completes, that information will be stored so the user may track their progress over time with a feature that allows them to lookup previous catalogs by date, which include their weight at that given point in time.
