David, I have split this off from the
Ipad & Iphone app (5487) thread, because I think it is heading in a different direction.
As
mjashby suggests, synching between different genealogy products requires an in depth technical liaison between the developers, and in most cases that rarely happens, because each developer wants to retain their commercial market share, so they protect the software interface needed to support synching.
It is really nothing to do with what platform the product runs on (Windows, iPad iOS, Android tablet, etc).
The best vehicle that exists for synching between products is
GEDCOM. I know it is not perfect, and each product tends to have its own
GEDCOM dialect, so some details get lost in translation, but without it the task would be hopeless.
It would help if each product at least fully implemented the glossary:gedcom|> GEDCOM Standard Release 5.5, but most do not. If you could persuade
Ancestry/FTM to do so, then that would be great, and would solve most of the problems. The biggest snag with
Ancestry is that it does NOT import/export
Media files with its
GEDCOM. I understand this is partly solved by using
FTM, which synchronises with
Ancestry, and does import/export
Media linked to
GEDCOM. Some work is in progress so
FH can support how_to:exchanging_data_with_ancestry_ftm|> Exchanging Data with Ancestry and FTM.
In the meantime, also see how_to:import_from_ancestry|> Import from Ancestry website and how_to:import_from_family_tree_maker|> Import from Family Tree Maker (FTM).
