A position information acquisition section acquires position information about a mobile terminal, and a storage section stores hour information and position condition information inputted to an interface section in association with each other. When the hour shown by a clock becomes the hour indicated by the hour information stored in the storage section, a comparison section compares the position condition information stored in association with the hour information, with the position information acquired by the position information acquisition section. If the position information corresponds to the position condition information as a result of the comparison, a notification section gives a notification.
