zero functionality (using iOS 7) – 3D PDF Reader Review

I just bought this to see if it would work. Of the three sample documents included, the .prc and .u3d documents came up blank; it crashed when I tried to open the .pdf document. Likewise, the app crashed immediately when I tried to open a pdf file with an embedded prc object that works well with Adobe Reader on my Mac laptop. When I opened the same document with Adobe Reader on the iPad, I saw no option come up to view the embedded prc object with the 3D PDF Reader app. In summary, this app exhibited no functionality; the best that can be said is that while it cannot open any documents, the attempt does not always crash the app.
