## What is ai ai umbrella?

It is a matching app with the motif of Aiai Umbrella, which is a Japanese custom. 
（https://ja.wikipedia.org/wiki/%E5%82%98#%E7%9B%B8%E5%90%88%E5%82%98）

From the nickname and location information of yourself and the other party, the distance between each other and the degree of matching of the nickname are quantified and displayed. Currently, it is a simple distance and character string matching process, but if the registration information increases, matching processing by AI analysis will be added.
