This app is a chat tool with Wi-Fi Direct.
Up to 6 friends can have a chat at a distance of about 20 meters!
For example, on the train, in the crowd, in the enclosed space and so on...
It doesn't matter if this place has the signal!

<< Story of the app >>
You got lost in another world of no chat!
You who like to chat have been trapped.
Let's chat in a situation where you are trapped!
If found by the grunt, the chat will be forced terminated.
Please keep talking away from grunt!
The watchword to avoid the grunt's attention is "lock".
Shout "lock"!
