Hello,
As the authors of FoxTrot Professional Search and Attaché, I just want to point out that we are indeed working on a new version but as it is a product that reads index files created by FoxTrot Pro, there simply has not been much more to add to it compared to the work done on FoxTrot Professional actually creating the index files.
We wish the App Store had a mechanism for demo versions so you could try it before you buy, but your exposure to risk is hoever imited to the 25$ US purchase cost for the application. I can tell you that our current internal build does work on the iOS simulator in iPad Pro size without having made any changes to the screen size code.
Regards,
