Is Android/S4 compatable ? If I make the move to Android from iOS I would love to be able to keep using the same accounts and not have to go through the import/export and change over to gmail/google for my contacts and calendar events
I've used DAV to access my contacts and Calendar on my own Personal Could Server, cutting the cord from both Google and Apple and it works fine.
