UI is terrible, but it works and does exactly what I need.

Wow, great app. A few (much needed) option providing better control/functionality. The developer does a tremendous job with support.

Only product I've find that correctly synchronizes. Developer is very responsive to all issues.

Does what all the others can't. You just need to work through it, after a short time you can see how logical the setup is.

Error with syncing and widget due to adding 1 hour to start time. Sometimes its correct, sometimes its wrong.

Free version worked like a charm. Moved over to this upgrade and have spent hours and it still doesn't work. Have asked for help and got nothing back. Going to try something else.

The only app I have found that reliably connects my CalDAV calendars to my Android phone calendar, UI is not pretty but it is functional with a ton of settings

App looks like it was designed by a blind person. Actually hurts my eyes to look at it. Don't even know or care if it works or not... can't bear to read the full-justified walls of text done in low contrast colors palettes. Please, dev... learn how to design a UI.

Excellent app excellent support one of the best purchases ever. Does everything you need it to. If you can't configure it the developer will personally assist you. Best in class.

Works perfectly to sync Outlook work calendar with Google calendar. Interface is truly hideous, but ended up being easy to set up if you read everything carefully.

The UI is certainly a little clunky, but once sorted out it just works. Been using it for a long time alongside Syncthing to sync the .ics file. Goodbye cloud calendars, hello personal storage.

Works seamlessly with my Synology NAS. Great tech support if needed.

Edit: it only worked a few hours 2 months ago. I think Annemarie gave up. The email support from Annemarie is great. So, yes, it's a lot to take in when you first install the app and it can be intimidating. It's easier than it appears. Scroll down to Manual & Tipps to start to get the step by step. I wanted my iCal to show up on my android. In options I used CalDav not cloud. That temp apple password goes in step 8. Syncnow manually in your new calend after each change and it's instant.

I had an issue with getting scheduled synchronisation to work in another CalDAV app, so decided to give CalendarSync a try instead. It works absolutely flawlessly. It is very easy to configure, and provides useful information about the status of each synchronisation attempt. I only wish that I had found CalendarSync first!
