Many foreigners living in South Korea faces various problems in their daily lives, such as language barriers, cultural differences, etc. This also applies to making food orders via mobile applications. A lot of foreigners have difficulties using food delivery apps for various reasons. The purpose of this study is to create a functional design of food delivery app for foreigners based on a survey. As a part of this study, we conducted a survey among foreign residents in South Korea to identify and analyze user needs. After analyzing the survey results, we proposed a mobile app design based on user experience. As a result, we created a new design interface that includes a full English translation of the entire menu and information about food allergens. Besides, information about nutrients, ingredient' origin, the pungency indicator and the label of vegan and halal food also have been added to the application interface.
