@selfhosted Self host phone contacts sync
I am searching for something to sync my phone contacts between multiple phones for some time. Best case it shouldn’t use DAVx^5 and should support Android and iOS. Thanks for your suggestions!
What I found so far:
Nextcloud - but needs DAVx^5
Radicale - also needs DAVx^5
SoGo - needs some CARD-DAV application
You may be able to use ActiveSync protocol to sync contacts to mail server like exchange or mailcow, though I never use it myself.
