Doesnt work with new apple ios 7.

I downloaded this app about a month ago. It worked fine on my Iphone 4s and Ipad when I got it. Once I downloaded ios 7, the app stopped working on both my devices.

Cant seem to find any support for this app. The support button just goes to a web page that describes how wonderful the app is.
