Help!!

I can’t even download the app!! I have no problems doing this with other games/apps. Just this. I would rate it higher if I could use it. Quidd sounds so awesome to!! Please help. I don’t get how to install it right. If you could give me some tip that would be greatly appreciated. Thanks in advance.
