What has happened?

I used to use this app constantly, and it must have been after an update, that now it wont even open. It was happening on my iPhone 4 so I deleted and tried it again multiple times, with no success. I then tried it when I got my iPhone 5 but still no success!

Has anyone else had this issue? Are the developers working on an update? Whats going on?
