DAVdroid is the only all-in-one synchronization solution for both contacts (CardDAV) and calendars (CalDAV). The app is easy to set up and integrates perfectly with your favorite calendar/contacts app (including default apps). It can also be used seperately, if you either have CalDAV or CardDAV.
Compatible with most CalDAV/CardDAV servers and services, including OwnCloud, iCloud and OS X Server!
