Re: FreeBitco.in - Win free Bitcoins every hour! - $30,000 contest now live!
This chap set up his own app based on free bitco.in sometime ago. I downloaded it in good faith but it never worked properly. I deleted it and it was mentioned in a thread about not downloading apps as they weren't official.
There is always a possibility that any 3rd party app may steal your login credentials. There is no official app so exercise extreme caution if you do use one. Some people have been very successful in marketing their apps and have built huge referral networks from them.
Roskomnadzor of Russia from July 1 began to block not IP sites, and sites that have game services. In one day, the activity of 22,000 sites with the presence of game services is prohibited. Block any sites with the presence of the game service. I'm shocked! 
That sucks to have a government that does that.
