DAVx⁵ is a CalDAV/CardDAV management and synchronization app for Android which natively integrates with Android calendar/contact apps.

Use it with your own server or with a trusted hoster to keep your contacts, events and tasks under your control.

For more information and a list of tested servers/services, have a look at the Web site.

Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos. For details on this, please see here.

Download Website Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
