According to Saudi Vision 2030, which aims to reduce food waste in the Kingdom, one of the methods to achieve that is an application, the "Na'am" App; the basic idea of application is to estimate the volume of food loss and waste in Saudi Arabia. By scientific methods according to international standards that help measure economic losses resulting from loss and waste in food, analyze the economic, social and cultural causes of loss and waste, comparing the magnitude of the loss and waste in food in Saudi Arabia with some other countries. Policies and plans can therefore be proposed to reduce the loss and waste of food in Saudi Arabia's Arab Kingdom.
