This is the app I created for the 2018 Congressional App Challenge.
The app is a calorie counter in which the user inputs their height, weight, age, and whether they want to lose, gain, or maintain their weight.
An example project on how to create randomise dice using variables along with containers and states to recreate various dice.
Use the + / - icons to add more of each dice. Includes all variations of basic polyhedral dice for use.
