DAVx⁵.
By bitfire web engineering
DAVx⁵ syncs contacts, calendars, and tasks between Android and CalDAV, CardDAV, and WebDAV servers. Address books can include photos, groups, and shared read-only books. Calendars keep recurring events, invitations, and time zones. WebDAV folders can be browsed and edited directly, including more than one cloud. bitfire charges a fee on Google Play and also points to free F-Droid builds.
The F7 Insight
Phone calendars and address books are more useful when they can live on a server you choose. DAVx⁵ is that bridge, including shared books and recurring events, while the phone's own calendar and contacts apps stay in place.
