[@selfhosted](https://lemmy.world/c/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
