Best way to sync app data between iPhone and desktop
There is a big number of apps now that have both an iPhone version and a desktop version. Usually you want to have the data in sync in both versions.
If the app doesn’t have its own web service as well (like Evernote, for example) then it usually resorts to various quirks that let you sync the data between the devices via wifi. That really is not convenient at all — you have to launch the app both on the desktop and the iPhone before the sync will happen.
So, what would be the most natural way to do the sync then? Of course, through iTunes, which already syncs all kinds of data between your desktop and your iPhone.
What Apple needs to do is to create an API for the developers to hook into this whole sync operation both on the iPhone and the desktop sides. An app can register itself in the sync framework and then an option to sync that app’s data would appear in the usual place in iTunes, you check it and it’s done — next time you connect your iPhone to your desktop the data for the app would be automatically synced.
