I have been using the application on my IPAD. Known problems are the inability to insert refills.
I bought the OS X eidition because of the advertized option to share data between devices. A total disaster, on OS X the application hangs when trying to import the existing data base (I had to reboot my MAC). Support was not helpful (wanted complete data base for their in-house debugging which is out of the question as it contains confidential data).
I don’t know how much time I’ve spend on this is so far, I’ll migrate to use a spreadsheet. Disappointing that Apple is not doing some basic testing
