This app has been invaluable for keeping my Android in sync with my iCloud *DAV services. This paired with BlueBubbles and OpenBubbles has made staying in the walled iMessage garden such a breeze. I can grab my iPhone or Android and everything just works.

I do wonder what apps people use for Contacts/Calendars though; recently I've been using the Fossify apps for a Samsung and Google free experience, but always keen to explore better options if they exist.

Still waiting for a good option for iCloud Drive access on Android, but the website works in a pinch.

Unfortunately not as good as https://github.com/alexbakker/webdav-provider for my use case

This is combined with Nextcloud allows you to sync Nextcloud calendar and contacts with your android phone. Meaning your contacts are now on your very own cloud and the calendar is synced as well.
