About this app

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/

If you read through the FAQs in advance and follow all applicable recommendations, as well as diligently follow the installation instructions, you'll be extremely happy with the ease of installation and efficient functioning of this app. Support is also excellent and timely. Use it if you get stuck. I had a couple initial issues that were both due my oversight. So if you have issues, don't be quick to judge the app without first seeking support to resolve.

I had a little difficulty connecting to my service, which is not on the list and whose own instructions for an earlier version of this software didn't work. I sent a support request and got a very cordial and prompt response from Bernhard with a solution that he had tested and found to work. It does what it's supposed to and with a very easy to understand interface and the developer offers the highest level of support. I'm not sure what else I could ask for. I'm a very happy customer :)

Calendar sync works well, but contacts sync does not work for the notes fields (using Zoho). Very disappointing. Everyone recommends this app but it would not sync contact notes. I have to use another app for contacts and that app works perfectly. UPDATE: I switched to storing contacts on my Synology NAS and this app works great with that platform. Must be a Zoho glitch.

That is unfortunate, can you tell us more about your setup? Zoho is used by many people together with DAVx5 without problems (at least normally)... support-en@davx5.com
