So far so good. It works great with our Owncloud server and my Galaxy S7 Edge. Update: It does not sync on its own I have to do it manually. I contacted tech support twice and they didn't give me any answer. Definitely not happy about it.
Loved app for a long while as it flawlessly worked w my aol calendars. However, since the last update on 6/27 (or possibly later) calendars stopped syncing & no entries now appear for present or any past months. I am running android 4.4.2 on my samsung galaxy S4. Would love some support.
I've been searching and tried various free apps that would sync my Yahoo calendar to a calendar app that I use and none of them worked, except this app. It's not free, but for a few bucks, I guess it's worth the money. And it seems to work well so far. Initial steps to set may have been bit confusing as I go to Yahoo site to confirm something then I found the settings that I expected. I'm happy with this app for now, but I shall see how it performs in next few weeks.
Update: The recent update has fixed its operation with Apple iCal Server. Now it's back to being the best sync for my phone & tablet directly to our iCal Server. Config was easy, just enter hostname & port (8443) and it started syncing straight off. Thanks Marten for tasks / to-do's support.
Have been using tis app w Zimbra servers for years, but autosync stopped working recently on several devices. No support reply in a week :-(
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
fix DIGEST challenge parser
fix occasional crash when setting up Google Sync
improve calendar update (should fix duplicate calendars with some servers)
