Regarding the application, I did try to check the one on App Store but what I see is like an app for sports prediction named cryptoin.
Checking the game will be better if you do it on browser than app IMO.
I would not install an application on my phone just for checking the game as it can be done through browser.
I am as well unable to locate their app in playstore. When I tried to locate their app by clicking the the playstore button under Download app in thier site, I am getting error page with the following URL

It seems they are not having android app for their house yet or there is something else like different key names needed to find it exactly (as I have seen similar problem with some other services).
Their site is loading very well on my mobile browser and the games looking good to play like how I felt when accessing on my desktop. So, it seems for those gambler to want to gamble on the go, accessing it on browser could be the currently possible way until they fix the app problem, it seems.
