One of a person's essential needs is food. Every year, an estimated 1.3 billion meals are created globally. However, one-third of all food produced for humans is wasted. The majority of food is lost every day in countless restaurants, gatherings, weddings, and other events. This paper focuses on creating a mobile application called DonateBite. This will help to address food insecurity and reduce food waste. There are lots of people who want to contribute food, but they are unsure about how to go about doing so. So, using our app, users can easily donate surplus food by posting information about the food items, their location, and their availability. Charities and individuals can then browse the listings and request donations that match their needs. The application may reduce food waste and provide food to those who cannot afford it, among other possible benefits. It can also promote community involvement and social impact by encouraging people to get involved in helping others and reducing food waste.
