Tried downloading the app in google play

https://play.google.com/store/apps/details?id=basic.heluss.com

But, I'm getting an application error -

"The connection to the server was unsuccessful. (file:///android_asset/www/ondex.html)"

Maybe, the app is not yet fully stable?
Interested to use this app as I might use this in my travels.

Update : Already installed and registered an account.
It says - I have 15 HUT tokens in my account. Is that a registration bonus?
