    CalDAV-Sync is a CalDAV client for Android to synchronize events and tasks. Due to its implementation as sync adapter it integrates seamlessly with the native calendar app and widgets. Also check out CardDAV-Sync

    To get task support, please install this task app

    Since version 0.4 CalDAV-Sync supports read-only sync of webcal ics feeds (via http & https).

    Important note for Android 4.1 and Samsung users: To prevent the removal of your accounts on reboot install this app:
    Although this issue seems to be fixed in Android 4.2 the workaround is still required on Samsung devices.

    Please note that there is a new issue in Android 4.4:
    It causes accounts to be removed when an app is updated. Installing the workaround app should help.

    This app will create new calendars on your device (one for each calendar on your server account).

    Please send me an email if you find a bug. Without detailed error description I often can't do anything especially when I can't reproduce it. It's also possible that your server has a bug that CalDAV-Sync can not (yet) tolerate or work around. If you report bugs I can fix them quickly and everyone will benefit.

    It is tested and works with
    - DAViCal
    - SOGo
    - Zimbra
    - OSX/iCal Server
    - eGroupware
    - Oracle Beehive
    - david.fx
    - iCloud
    - ownCloud
    - many more, see for a list of all servers reported to work

    Note to Yahoo! users: Due to the many issues on Yahoo!'s servers, Yahoo! is no longer officially supported by this app.

    Note to users: doesn't support CalDAV. However you should be able to sync your calendar one-way using the Webcal option.

    After the installation got to "Settings" > "Accounts & Sync" and create a new Account.

    If there is no calendar installed on your device, go to my website and install CalendarProvider.apk and Calendar.apk (FroYo and Gingerbread only)

    Once this app reaches version 1.0, I'll make it open source.
    See for details on the open source status.

    Gantastic app, but most importantly supported by the developers, when systems are updated, it's not long before an update is released, app makes working with Apple / icloud outside of apple possible and simple

    After an app or system update, I now keep getting a popup error message stating "CalDAV-Sync keeps stopping" randomly and frequently (15-60 seconds) :-( This has been a critical app for me for quite a while now but I'm very disappointed in it's stability as of late.

    It is unfortunate that with all the resources Google has at their disposal, they still cannot justify adding support for the Calendaring Extensions to WebDAV ("CalDAV") Internet Standard... But this is where CalDAV-Sync comes in. Not only does CalDAV-Sync fill an un-necessasary void, but the application looks great and thus far, has worked flawlessly for me. If you're an Android user and you need support for CalDAV, then look no further than CalDAV-Sync!

    This was, until recently, an excellent product. However, a recent change to the SSL cert used by my Baïkal CalDAV server exposed some serious problems. I can no longer connect to the server, even after removing and reinstalling the app and recreating the connection account. This may or may not be the fault of CalDAV-Sync (my Mac desktop apps have no trouble connecting), but the trouble is, the debugging messages don't describe anything useful about the SSL connection, so there's no way for me to tell. I can hope that the developer can expose more of this info in the debug log, but in the meantime, I'm forced to find a different product, as this has completely cut off my calendar and task lists.

    So far so good. It works great with our Owncloud server and my Galaxy S7 Edge.

    Does exactly what's it's designed to do.
