Its just not working??

I saw this game and I thought it would be really fun, and similar to Love Live School Idol Project, so I went ahead and downloaded it. When I tried opening the app the screen was just white. I waited a few minutes and uninstalled the app and tried again later but it was still just plain white. Im super sad I was really looking forward to this game. I have the right generation and it says it works on iPod touches, so Im not really sure whats wrong.
