I have checked it and it looks very interesting to wait for the global launch
The teaser in the google play looks very good.
I hope that the exact date for the global launch will come as soon as possible too. I will try do download it when it will available soon.

If the team has launched an application for the global I think a lot of people will download this application and more widely this project is known. Maybe the team should also do marketing when the launch is done.
Ohh btw, is the airdrop website under maintenance? I can't visit it
