Hey Product Hunt š I'm Myroslav.
I live in Notion, but my day actually happens in Apple Calendar. Every tool I tried just gave me a read-only webcal feed that refreshes whenever it feels like it, and you can't touch anything from the calendar side.
So I built Calnio. It writes real events straight into iCloud and syncs both ways: move an event in Calendar and the due date moves in Notion, rename it and the page gets renamed, create one and a new page appears.
It's just me building it, it runs on a Raspberry Pi at my place, and it's free.
I'm not here for the badge, I genuinely want feedback:
ā What breaks?
ā Anything confusing in setup?
ā What should come next: Reminders support, Google Calendar, or something else?
I'll be here all day answering everything š
