I built a two-way sync between Notion and Apple Calendar launching on Product Hunt today

Hey! Solo dev here.

My tasks live in Notion, but my day happens in Apple Calendar. Every tool I found only offered a read-only webcal feed, so I built Calnio.

It writes real events into iCloud and syncs both ways:

- move an event in Calendar -> due date moves in Notion

- rename it → page gets renamed

- create an event → new page appears

It runs on a Raspberry Pi at my place and it's free.

Launched on Product Hunt today would love honest feedback there or here: what breaks, what's confusing, what's missing.
