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.
That’s actually easier than on android, we need a caldav sync provider app.
Like DAVx5?
Yes.

Do you need one app for syncing caldav and another app for using the calendar?
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)
Caddy makes HTTPS a breeze. I’ve tried nginx before but I never understood when and why I would need which setting.
I don’t have a registered domain for my laptop server (and hence cannot use HTTPS) as I find that I don’t really need it for my use case. Using Tailscale is fine for me if I really need to access it remotely, but I mostly use it for backing up files and images on my local network, and calendars can sync once I get home.
Would a self signed certificate be an option? Not sure if the hassel is worth with the applications on the phone.
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
