CardDAV-Sync free

CardDAV-Sync is a CardDAV client for Android to synchronize contacts. Due to its implementation as sync adapter it integrates seamlessly with the default contacts app.(Also check out CalDAV-Sync)
Samsung S5 users: Please note that some S5 devices come with a broken contacts app that crashes when opening a contact synced by this app. Please report any crashes to Samsung.

HTC One users please check out this site first: http://dmfs.org/wiki/index.php?title=HTC_Sense_issue

Please do not install the Workaround app when you use the free version of CardDAV-Sync. It's for the paid version only

If you find a bug send me an email, please. 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 CardDAV-Sync can not (yet) tolerate or work around. If you report bugs I can fix them quickly and everyone will benefit.

Also check out the paid version CardDAV-Sync. It syncs some additional fields (like company/organization and notes). For details see my website.

Please uninstall the free version before you install the paid one (and vice versa).

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

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

Important! If your phone removes the accounts on reboot, move the App back from SD card to the phone. Some phones (if not all) can't handle sync adapters on SD Card properly.

For users who are unable to edit or create synced contacts I published an editor at the market. Just search for "Contact Editor" or see my website.

Once this app reaches version 1.0, I'll make it open source.See http://dmfs.org/wiki/index.php?title=Open_source_status for details on the open source status.

Features:


* Sync contacts from a CardDAV-server (tested and reported to work with DAViCal, SOGo, egroupware, Zimbra, david.fx, Fruux, ownCloud ... and more. See my website for details)


* basic support for self-signed certificates


* auto-provisioning


* two-way-sync


* syncs names, phone numbers, email addresses, postal addresses, photos and birthdays (but please visit "date formats" on my website first)


* automatic address book discovery (works with most servers in default configuration)


* one-way-sync of Apple-style groups


* Support for Apple-style custom labels (X-ABLABEL)


* stores passwords encrypted


* supports efficient sync-collection request

It is still under development and some important features may be missing. Known limitations are:


* organizations, instant messengers, categories, notes and websites are *not
* synced by the free version


* SOGo Contact lists are not supported yet (work is in progress)


* only "server wins" and "phone wins" (default) conflict resolution available (that is when a contact is updated on server and on phone between two syncs)


* and maybe more

Please report bugs. Feedback is very welcome.

Btw: just writing a comment like "Doesn't work on..." won't help neither you nor me to get it running on your device. Please contact me if you have problems.

known issues:


* @david.fx users: david.fx returns all links to contacts from sub-folders. Currently this leads to the situation that some contacts may appear multiple times (joined to one contact)

Allows me to sync my contacts to my cardav server just fine, but does not reliably sync on a schedule. I have to manually sync every few days. Also, if you change your password to the DAV server, you need to delete the server in Carddav sync and re add it. overall, it's a free app and works well, aside from those two things.

Free do come with a cost. This one will not sync all the fields of your contact. And paid version also does not have calendar sync. So better look for other options.

Sha. H. Feb 21, 2019     

previously had some issues with this app but it seems that in some cases the app requires you to set the "Use preemptive authentication" checkbox. To do this after choosing "CardDAV", click the ⋮ icon in the upper right. Now the account setup should work correctly.

Been told by app that is was build for an older system version (I have Android 10/MIUI 11). So, after the latest system update I got stuck synchronizing my address book stored on Posteo servers...

Best - Simple & Adfree app!! I used it for my android devices. Even though too simple without some important settings like edit name. But it was usefull to sync my icloud contact across my devices

Dav. C. Jul 4, 2021     

Still working even though it hasn't been updated since 2017. Syncs well with no issues.

Ada. F. Nov 10, 2019     

Has had no updates since Android 5. Now it wants to charge me again even though I have already paid for it. Probably used a name change for that scam.

Interface isn't great, but it works, free and no ads!

Jus. A. Apr 3, 2020     

Unfortunately the app hasn't been syncing since the Samsung's March security patch.

Inf. Sep 9, 2019     

Synced all contacts okay, but it swapped the Forename and Surname around on the contacts

Abo. B. Jun 26, 2021     

This helpful app all your contacts in one place after singing that's good

Tom. A. Apr 13, 2020     

Contacts have stopped syncing or only partially sync

Luk. Jan 19, 2021     

Doesn't work on Android 10

Tre. J. Nov 7, 2018     

It actually works! Such a shame that that's the bar in this app category.

Mak. S. Sep 30, 2018     

A good app to synchronise your contacts two-way via CardDAV with various services

Joh. L. Sep 26, 2020     

Not all the features worked.

App asks for server certificate confirmation and then crashes

Work very smoothly to me

App has been abandoned

A. G. u. Jul 5, 2018     

Works with iCloud when you use app specific passwords. I finally went to the 2step authentification annoyance, and it was easy to set up and sync. 2 problems: does not sync all the pictures and the count is not the same. I think that's due to the way Android counts merged contacts. I have used CalDav-Sync since 2010, so I chse this Devs Card sync, and it works.

Mar. S. Jan 21, 2018     

Auto sync broken since many months. Developers are aware but are not pushing out a fix. Just use DavDroid, which works fine.

A. G. u. Jul 11, 2017     

Created many mail accounts, not one worked with this app. Waste of time and probably mining username and passwords.

Raj. P. Jul 28, 2017     

Just tried it. Seems easy to set up. Have not understood the limitations yet
