Have you ever wasted food, and what do you do with it when it's about to go bad? How do we design an app that helps users find ways to comply with the California Food Donation regulation (low) and be verified by mobile device users to help users address the root causes of food waste? AirSupply is an app for mobile device users. It will manage user purchasing behavior, and help users save money through data analysis of food donations; through food donations, donors can also easily print tax-deductible receipts through the platform. And create user incentive systems for these Spaces to help other mobile device users join our platform.
