Both PC and Mac Logbook version 9 now run on iPhone or iPads using iOS 5.1.1, with FileMaker Go 12 or 13 already installed. The 'logbook9.fmp12' file needs to be downloaded AFTER installing the FileMaker Go 13 App (available free from the App store).
Logbook Portfolio reports are all now accessible to view, save and email from within the iPad/iPhone app. However limitations to the FMG App mean that previous cases need to be imported via the PC/Mac versions of the program BEFORE transferring the 'logbook9.fmp12' file to the iPhone /iPad.
