Not bad!

This app works perfectly on my old iPad 3. I have two iPads, an iPad 3 and an iPad Air, I didnt upgrade my iPad 3 because I want to be able to use two versions of iOS ( well, iOS 7 on my iPad Air has a few bugs like sometimes rotation stops working etc.) So, the app is totally compatible with my iOS 5, havent tried it on my iPad Air yet.
