In the App Store from apple there is PDF Nomad version 1.3 from 12. April 2012 available.
On the SintraWorks webpage there is a version 1.3.1 and now 1.4.
Why it takes so long ( nearly 3 months now) and the App Store version is still not updated or is there never planed to update it ??
I have the problems here with the 1.3 and crashes after saving a document.
