This app is a search request from family members and facility managers saying "I want you to find a dementia patient because he is wandering around and missing", and "I will cooperate with the search" within a radius of 5 km from the place where the call was made. It is an application that connects people who have the intention of cooperation. * This app collects current location data even when the app is not in use, in order to enable the notification function for neighborhood search requests
