This app is not working waste of a $1.99

I have a new 4s and I too have downloaded the app and redone loaded it and I cannot get pass the registering screen. It stays stuck on registering and then I close it and it opens up with connecting. There is obviously something seriously wrong with it and I will be trying to contact the developer for my refund. I have screen shots and am not the only one with this buggy problem. :-(
