Boarding house owners promote their boarding houses in a conventional way, namely by word of mouth, distributing brochures, or posting announcements in public places. Based on these problems, an Android-based boarding house search application is needed, an application system that can be a place for out-of-towners who feel confused in finding boarding houses that suit their wishes, and can help boarding owners promote their boarding houses online via a smartphone based on android.

The results of the research resulted in a boarding house search application that makes it easier for users to find boarding houses according to their needs and also this application can provide information about boarding facilities and this application can also make it easier for boarding house owners to publish their boarding houses.
