About Project

Macrozone is a small mobile project built to learn the fundamentals of React Native and Expo through a useful, focused feature set.

The app has three tabs: Home shows the day's calorie and macronutrient totals with recent meals, Add Meal captures a meal's calories, protein, carbohydrates, and fat, and All Meals displays the saved list with an option to clear it.

Meal data stays on the device through _AsyncStorage_. The project also explores native capabilities through local meal-reminder notifications, summary sharing and copying, and haptic feedback for interactions.
