Food-sharing apps are digital platforms that connect people who have surplus food with those who need it. These apps aim to reduce food waste by allowing users to share excess meals, groceries, or ingredients with others in their community. Users can easily list available food items and browse offerings nearby, promoting sustainability and helping those in need. Many food-sharing apps also partner with local businesses, such as restaurants and grocery stores, to redistribute unsold food. This collaboration not only benefits users but also helps businesses minimize waste and contribute to social causes. Popular examples of these apps include Too Good To Go and Olio.
