FileMaker Go Logbook
Both PC and Mac Logbook version 8 now run on FileMaker Go 11 (but not v12) for the iPhone or iPad. The 'logbook8.rca' file needs to be transferred via iTunes sync. after installing the FileMaker Go App.
NB FileMaker Go is great for data entry, but has limited reporting capabilities, so you will need to transfer the 'logbook8.rca' file back to a PC/Mac version to gain access to the full range of logbook reports.
