    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.

    This app would never auto-sync for me. I was prepared to live with manual syncing. But when I installed Android 7.0 very soon after I bought this app, it crashed every time I tried to sync. I sent two very polite emails with all of the required info to the app support (the second one was sent well after the expected response time stated in the autoreply had elapsed) and still haven't gotten any follow-up one month later.

    Exactly what I was looking for. I wanted to sync my work owncloud calendar to the standard Samung Calendar. After lots of googling and trying other stuff out, I found this and it worked straight away. Great app. Thank you.

    Was stumped trying to get my AOL calendar to link to my Note 8. Installed this and was good to go in less than 5 minutes. Awesome, thanks.

    Automatic sync stopped working. Makes this kind of useless. Android Oreo.
