I already own MobileFamilyTree 2, how can I change to MobileFamilyTree Pro?
MobileFamilyTree Pro is not an update, but a new development. Apple does not allow chargeable updates via the App Store. Therefore it is not possible, to grant a discount for existing customers. If you would like to use the first full fledged genealogy application for iPhone, iPod touch or iPad, the normal price is charged. Of course you can also use MobileFamilyTree 2 further on.
More information is available in the User Guide. You can find it in MobileFamilyTree Pro´s Help Menu or for download here.
