Call of war mobile

I am so sick of having to turn on my PC to be able to check on my games. Lately I have been playing call of war on my iPad, but I don't always have access to my iPad. I would like to play call of war on my phone, but when I log in the game doesn't fit my phone screen and I can't drag the screen. I think we seriously need an application for App Store and google play. We all want it
