Unable to be used in iOS7
This app was very good for me to take my 3D models with me to show my colleagues at relevant meetings. I did recommend this to colleagues for their use at that time. This app will not display any 3D models in iOS 7. I contacted the developers in October 2013 regarding an upgrade for iOS7. They stated this would take a few weeks. There has been no update 3 months later. I would no longer recommend this app to anyone.
