Introduction

Almost all of the social networks are designed based on the relationships between every people. But sometimes, to some social demands, the first thing need to be considered is not the relationship between the other people and me, but the distance between us. Like second-hand selling, car crash reporting, first aid and so on.
So, we designed this Instant News Application based on the location.
