No matter - i checked their site now and i think they are only scam !
On the site you can find almost no information ! It is only a ONE-PAGE website .
Also on their website you can not find any information how an app publisher can earn money with them!
Also no adress to find on website, no facebook page, no twitter-page, no google page - absolulty nothing !
The app itself is also a joke - 100000 downloads only !
I will NOT use them - because they are never legit and maybe even scammers !
