It is an application that makes it easier for someone who has lost something to find it easily by searching for lost items found by someone by specifying the location of what was lost, such as the country, city, and place. If it is not found, the location of what was lost is specified, such as the country, city, and place, so that the person who found the lost item can contact its owner. Also, the person who found the lost item can return it to its owner in the same way that the person who lost their lost item searched.
