Description

If you're encountering problems please contact us: support@davx5.com or have a look at our forums: https://www.davx5.com/forums/ instead of down-voting the app so that we can provide support.

DAVx⁵ is the only all-in-one app for all things CalDAV, CardDAV and WebDAV! It is a fully-featured sync solution for your contacts (CardDAV), calendars (CalDAV) and your tasks (based on VTODO). 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, CardDAV or only Tasks. DAVx⁵ can also be used to access your remote WebDAV files.

Want to keep track of tasks, notes and journals? Try jtxBoard:
https://play.google.com/store/apps/details?id=at.techbee.jtx
DAVx⁵ can synchronize everything from jtx Board with your own server!

Compatible with almost every CalDAV/CardDAV servers and services, including Nextcloud, iCloud and Synology!

After installing, you can add a DAVx⁵ account for CalDAV and CardDAV from within the app. See https://www.davx5.com/tested-with/ for help. For more information, please see the manual: https://www.davx5.com/manual/, the FAQ: https://www.davx5.com/faq/ and our forums: https://www.davx5.com/forums/

v4.5.19-gplay

Very very very useful. PSA: use this to sync more than one year of events from your Google Calendar. Much cleaner than other hacks and tricks. (Disable regular sync-ing in Settings -> Accounts.) Also works to sync iCloud calendars.

I've been using this app to sync my calendar and contacts, it works flawlessly, thank you

Advertises itself as something that's different from what I wanted. On the main website it advertises two-way sync, but that's for CalDAV and CardDAV, NOT WebDAV. I only wanted to use this app for WebDAV, but it's a third party citizen in this app, offering no WebDAV sync functionality at all.

Developer Response

That's true - there is no sync function for WebDAV. We do also not advertise a WebDAV sync anywhere. We advertise "Access to your WebDAV cloud files" (what it is) and "Sync your Contacts, Calendars and Tasks".
