Valuable utility – Contacts Backup - IS Contacts Kit Free Review

Makes backup of contact data, independent of Apple, fast and easy enough that you can do it routinely, whenever you add a new contact, without interrupting your work. Also great for manually syncing your phone and with contact lists on your computer or email server; in my case at least, these lists need to share some contacts but aren't identical, and the import/export features of this app let me control what goes where. Works fine with a Synology NAS.
