I just tried to move to Android because it's more open. Was not prepared for the "open" OS to not have basic support for self-hosted calendars. Yes, contacts and calendar are a core OS level feature in 2026.
Yes DAVx5 exists, but Google Calendar was buggy with local calendars and DAVx5 actually didn't work reliably afaict.
Calendar.app is totally seamless with synology on iOS. Same with contacts.
Android was working overtime to make sure I use Google for everything. iOS isn't perfect but I don't have to jump through crazy hoops to be in control of my data.
Exactly that. It's mind-blowing, to be honest, because I hear Android fanboys claim the system is so much more open, when it reality it's a mixed bag: iOS is more open in some areas, Android in other, but it's not a clear-cut case at all. There's some hope in EU making them be more open, at least on some fronts, e.g. https://www.heise.de/en/news/Google-EU-demands-Android-be-op...
