APDL and Logbook Pro are two completely separate logbook solutions. APDL is strictly for airline pilots / FAR 121 'duty/scheduled' flying. Both lines will continue with no intention of stopping or changing either except for improvements. The Logbook Pro version 2 line, whenever that comes, will have improved/new interface, features, you name it, as will APDL version 7. Again, these two product lines are related ONLY by the fact that they sync to the Logbook Pro PC product.
