Health Tracker App – Short Explanation (MIT App Inventor)

The Health Tracker App is a mobile application developed using MIT App Inventor that helps users monitor their daily health activities. The app checks the user’s walking rate (steps or activity level), tracks calorie intake, and displays a food chart to help maintain a balanced diet.

Users can enter daily food consumption and activity details, and the app calculates basic health metrics to give an overview of their fitness.

This app promotes healthy lifestyle habits and helps beginners learn how to use input components, sensors, lists, variables, and basic calculations in MIT App Inventor.
