I just installed Radicale and could not at first figure out how to add a calendar that I could edit in the app. And since I could not find any decent post on the topic, here is how to do it (as of iOS 18.7.3 on an iPhone 13 pro, but I imagine the process being very similar on other devices):
- Open the Settings application.
- Scroll to the bottom and open the Apps options.
- Open settings for the Calendar application.
- Open Calendar accounts.
- Add a new account.
- Chose “other”.
- Chose “CalDav-account”.
- Enter URL and credentials for your Radicale server.
I have SSL set up with Let’s Encrypt managed with Caddy so that was all I had to do. I say this because I read one discussion about SSL being needed.
Yeah, on Android you use DAV5x or something for syncing, and then another app for calendar (I use Etar). I think DAV5x also acts as an intermediate for smartwatches for calendar notifications, but haven’t verified this, it’s just a hunch of mine. I think it’s probably for ease of development, so the same CalDAV thing doesn’t have to be redone over and over again.
As a previous iPhone user, I liked that it was in settings (I did not like, however, that I wasn’t able to set up Radicale on my iPhone at all since I didn’t have HTTPS with my laptop server. I guess something something security no options for you. If it worked for you that’s great! Working things are good)
I also didn’t like that on iPhone a majority of the useful settings are buried in dark corners that are difficult to find. Not very helpful at all
