Since social activities of the modern people have increased continuously in recent year, many people frequently communicate with each other online and/or offline, exchanging a variety of information. Thanks to the development of smartphones and a wide range of mobile applications helping social activities of people, people can communicate more easily beyond their time and space. But, there are not many mobile applications specially designed for effective communication and collaboration among co-located people, most of the existing applications only provide limited functions. In this paper, we present an android mobile application DIO specially designed for co-located people to collaborate in a rich way. DIO enables users to share and exchange their profiles, favorite photos, musics, videos and documents according to one of the three open levels - public, business and community level. In addition, through DIO, co-located people can chat, vote, and survey. DIO is implemented on the top of AllJoyn platform - an open source IoT platform developed by the AllSeen Alliance. So, it can be easily done to extend DIO to communicate with other smart things running on the same platform.
