DAVx⁵ is an open-source Android app that synchronizes contacts, calendars, and tasks with CalDAV/CardDAV servers and provides live WebDAV file access. It is privacy-focused, works with self-hosted and commercial servers, and integrates seamlessly with Android's native calendar and contacts apps.
Use cases
- sync android contacts with a nextcloud carddav server
- sync calendars between android and a self-hosted caldav server
- access webdav cloud files on android
- sync tasks with caldav vtodo
- replace google contacts/calendar sync with a privacy-friendly option
- connect android to radicale or baikal servers
When to choose
- you want two-way CalDAV/CardDAV sync on Android with a self-hosted or privacy-respecting server
- you need WebDAV file access integrated into Android's Storage Access Framework
- you want an open-source, actively maintained sync client with wide server compatibility
When to avoid
- you need Exchange/ActiveSync or proprietary Google sync protocols
- you are not on Android (it is a mobile app, not a server or desktop tool)
- you need a library to embed CalDAV support in your own app (use dav4jvm instead)
