DAVx5 – Contacts, Calendars and Tasks Synchronization on Android
@DAVx5

With DAVx⁵ it is possible to synchronize your contacts, calendars and tasks on your own or with a trusted server of your choice. It makes it possible to use your Android without any Google services - but with the ability to still have a fully working and reliable synchronization that integrates seemlessly into Android. It is based on the complex protocols CalDAV and CardDAV. A lot of providers and servers use these protocols. Please find more information on our official website. DAVx⁵ is open source software (GPLv3).
