Welcome to Apple Discussions.
Information Appliance Associates, the publishers of the PocketMac software line, do not offer a Palm solution. The party who referred to them must have actually been describing the
Missing Sync for Palm OS from Mark/Space:

It is not required, but it is a much more flexible, configurable and reliable program than iSync with regard to the synchronization of Palm handheld organizers and smartphones.
Like iSync—which is used to synchronize your handheld with iCal and the Address Book—it provides an alternative to the Palm Desktop PIM. Unlike iSync, it provides three conduits—Mark/Space Contacts, Events and Tasks—and does not require either the Transport Monitor or HotSync Manager to handle synchronization events.
You can find many more posts regarding all of these applications in the iSync discussion area, here:
