Make real communication more fun with surprises and excitement in the real world. This is a management application for the Show+ service, which is a new SNS type signage with bidirectional transmission. This management app allows you to create event content distributed through the Show+ service, set distribution schedules, and control signage. Show+ does not require any special signage equipment and anyone can easily use it with their own PC, tablet, or display. It can be used easily and affordably in a variety of situations, such as entertaining at weddings and parties, as a tool to attract customers at stores, as a work tool in workshops, and as tourist information.
