Works exactly as advertised I downloaded this app and followed the installation instructions on the wiki. Everything was super smooth and within a few seconds, I was able to view my self-hosted calendar, which uses the Radicale server. Two way sync also seems to work properly. UPDATE: Dropping a star because it ate up 20% of my battery for the initial sync and then continued to be the highest battery consumer.. even more than the screen!!

In general a great app. I use this app to sync my cakendar with my RaspberryPi running a Baikal server. In most cases that works fine. But sometimes the app does not sync anything and remains in that state until the CalDAV-Account has been removed and created again (a bit anoying). An other issue is that sometimes the app keeps showing the "Cancel Sync" button although thr sync is already completed. Hitting the button does not do anything at all - but by that you cannot sync manually as the needed second button is disabled.

Very slow Takes half an hour to sync calendar, of which 10 minutes without any network traffic whatsoever. You can never be sure that everything has been synced. UI only allows to add an remove accounts, but not to edit (or even view) existing accounts

Works Great Except.... I love this app, it works great with my owncloud setup after a long learning process. I've been using it for many weeks without any issues EXCEPT, i had to go through and re-configure all of my owncloud user passwords. The App doesn't like using passwords with special characters (I didn't do any research to figure out if it accepts a select few special characters). Making a dozen users change their passwords after the fact is a real PAIN. Bottom line, great app.

That's what I needed :) Thank you for this great app. Now I can synchronize my owncloud calendar on my raspberry with my smartphone. But I found a little Bug: if there is a "%"-sign in the URL, the upload to server doesn't work. If I remember correctly, the app responded with Error 51.

Only syncing one way Not able to see yahoo calendar events created from other devices. Only able to see events created from the phone. This app hasn't been updated in over 6 months. Does the developer have a fix for this issue?

Almost the good one The sync with Zimbra 8 works and it's the only free app that does this that I've found so far. However, there is a problem with recurrent events. If one of them is changed (but not all of them), the change will have no effect on the events imported :/

Great calendar sync Works very well maybe too well... Can we have a way of turning down the sync... Every minute it synchronized .. Little bit excessive? Nothing has changed .. Maybe have a option to change the frequency? But apart from that loving it and well bloody done mate ;)

After some problems, it started to work again Don't know if an app update fixed it or simply the time (our company servers were not touched)

Android Device Does Not Dynamically Sync with iCloud 11/26/2013 - I tried many configurations and couldn't get any of them to work. I did a little research on how to configure this and it works perfectly. Now I can update the calendar from any device, IOS or Android, and all other devices that connect to iCloud are in sync. 12/3/2013 - Not sure what has happened but I went to set an appointment today on my iPhone and it will not get through to my Samsung Note tablet. I do see the event in the iCloud calendar and it goes to the other IOS devices just fine. The only resolve is to delete the Caldav account and recreate it. Once I do that it will sync everything in the iCloud calendar to the tablet but the same problem occurs if I try to create a new event in my iPhone. I am running v 1.8.1. I will check if another release is available but I have to downgrade this rating to 3 stars until some progress is made.

Doesn't sync from radicale Seems like it would be a great app if only it would sync from Radicale. It sees events that it creates but none created by other clients. Even other Caldav Sync Adapter clients. I've created issue #183 about this so anyone else having this issue can follow along at https://github.com/gggard/AndroidCaldavSyncAdapater/issues/183

Finally found what I was looking for Works like a charm! But what is the frequency of the sync? Is it 20 minutes? I see that manual sync works well. But is there a way to sync more frequently (automatically)? Reduced one star since I am unable to tell the frequency of sync. Seems to have a mind of its own.

Works Great I was able to connect to my company calendar. That's all i need. I also can sync two ways (but i don't need it, only syncing from company) Great!

It works as advertised. Much better than earlier version. (I had uninstalled earlier version out of frustration) The only issue I see now is it can't detect an exception to series invites. viz I got an appointment, which repeats every Friday. Due to some reason only today's event is rescheduled but I can't see that change in my calender even after repeated syncs. Looks like some bug with this app which needs a fix.

Not working on 2G and Crashing Play Store For me App is not working in 2G mode. And on WiFi or 3G, whenever sync happens AppStore gets crashed, always. If I disable auto sync on this app, then appstore won't crash.

Works fine until you change the password Did get it setup relatively pain free, but once my source account changed password there's just no way to change it in caldev without setting up a brand new account and waiting for it to sync everything again. With that change implemented it'd be worth an extra point or two.

Great app. Works fine on my Samsung Galaxy S4 mini. Thank you. Request for enhancement: If the account password changes, then I need to remove the old account, re-create a new account, perform a full sync.

Good one I was looking for similar app since a very long time, finally i got it. One issue though - it does not sync updated or deleted events. It only syncs new events.

Doesn' t work for me Keep getting error "Caldav sync error (general)" on my HTC Desire S Android 4.0.4, HTC Sense 3.6 Connecting is successful, and it says new calendar found : MyCalendar. Immediately after that it throws the above error.

Doing nothing Installed fine, easy to set up, found my calendars on the server, said syncing then said synced… and nothing showed up! Nothing, no calendar entries at all! Jellybean 4.2.2.

Free & Awesome! Great free way to sync CalDav servers. Although one thing that would make it better is the ability to set sync intervals. Right now it syncs once a day

Works well with zimbra and S3 Works well with Zimbra 8.0 community - two way. One star down for the ui or the lack there of but for all intents and purposes it does an excellent job!!!

AKB I don't know why its rating is so low. Only free Caldav app on play store,completely working. Don't know what else anyone want.

Eats battery and crashes often Previously. .. Worked fine so far and meant I didn't need to download Touchdown bloat ware.

Great App for Simple CalDAV Sync I wasn't keen to use IMAP to connect to my work account because it enforced device lockscreen policies. This sync adapter is perfect because I just needed my calendar when I'm mobile and don't need to check e-mail as often. The calendar was picked up by Google Calendar and my calendar widget.

It works great The only difficulty I have is with account removal: once I set multiple accounts I'm not able to remove them

Only half works Tried to use to sync ycalendar (yahoo) with calendar app on SG4. Can add events (will sync to web), but cannot see any events added from other devices. If dev has a fix, I'd like to see it. Thanks.

Not syncing It was working great, but it stopped recognizing my user info for my Yahoo! account. After re-entering the info, it just won't sync with the account again. Why won't it sync to my Yahoo! account anymore? I'm going to have to remove it.

Works brilliant Works brilliant with Lollipop and Sony Experia Z2. Is it possible to add a chooser for the synchronization frequency? This is the only thing I am missing.

Not working for me. I notice there's no option to specify SSL or no SSL. when I try to use it I get "invalid server answer, check URL" I have verified the URL and still nothing.

A couple of bugs Works great but there are still a few bugs. For example, if it cannot connect it kills the battery.

Can't Even Set it Up Please help me set it up! It is downloaded by appears nowhere in my phone.

great stuff doesn't quite work with sogo and editing instances of series events: duplicates and ghosts. good enough though.

Simple and does it's job Great app... It's free and simple and does it's jobs. I'm using it Davail to access my work calendar. It can see all my calendars. Con: Cannot change credentials. As most corporate accounts force you to change your password every month, I need to delete the account and then re-add with the new password. It would be nice to be able to edit the account.

No sync for AOL Calendar Did everything right and does not work. Please advise

Not with google I'm trying to solve problem with my new phone that refuses to sync calendar with google. This app works well with owncloud but not possible to work with google caldav. I think it is because it does not suport Oauth 2.0 protocol that is now mandatory for google acces.

Does not work with Yahoo While I can set up the account ok and it states that sync has worked, no data is every pulled through to whichever calendar that I use for Yahoo Calendars. Annoying, but I guess it's down to Yahoo.

This used to work for me, but now I cannot get a connection to my Baikal calendar anymore. Anybody's got any tips for me? Running Android 6 now.

Works I was having a few issues with Google calendars, so I signed up for a free account at owndrive. Seems to sync kde/osx/android OK; I can't seem to set sync intervals though...

Works Does what it is supposed to.However it causes very high data usage and there's no clear way to adjust this. Update: I recently tried to install it on a new Android phone, and it gave me "invalid server answer, check URL" when attempting to use with Yahoo calendar.
