Calnio syncs Notion tasks and Apple Calendar both ways, real iCloud events with alerts, not a read-only webcal feed. Edit in either app, the other updates. Free, built by an indie dev and hosted on a Raspberry Pi at home.

Hey Product Hunt 👋 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: – What breaks? – Anything confusing in setup? – What should come next: Reminders support, Google Calendar, or something else? I'll be here all day answering everything 🙌
