Made a free two-way sync between Notion databases and Apple Calendar

I plan everything in Notion but live in Apple Calendar, and the existing options were all read-only webcal feeds that refresh whenever they feel like it. So I built Calnio: it syncs a Notion database with an iCloud calendar both ways. Dates, renames, new and deleted events go in both directions. Real calendar events, not a subscription feed. It's free, built and hosted by me (solo dev). Looking for people to try it and tell me where it breaks. calnio.myroslavrepin.com submitted

痛点：Notion 规划用户与 Apple Calendar 用户之间的同步大多只能通过只读 webcal 订阅，刷新时间不可控，无法双向更新事件。

目标用户：重度使用 Notion 做规划、同时日常使用 Apple Calendar/iCloud 日历的个人用户与效率工具爱好者。

证据：existing options were all read-only webcal feeds that refresh whenever they feel like it. So I built Calnio: it syncs a Notion database with an iCloud calendar both ways. It's free, built and hosted by me (solo dev). Looking for people to try it and tell me where it breaks.

变现：免费增值：免费支持单个 Notion 数据库与基础同步；付费解锁多数据库、团队协作、高级过滤、冲突解决、历史版本、更快同步频率或一次性买断。

MVP：2 周 MVP：用 Notion API + iCloud CalDAV 实现标题/日期/新增/删除/重命名的双向同步，提供简单 Web 配置页和 App 专用密码/OAuth 引导，先服务个人 Apple Calendar 用户。

竞品：Notion Calendar、Zapier / Make / IFTTT、CalendarBridge、Reclaim.ai、Fantastical / BusyCal

摘要：Reddit r/SideProject 上独立开发者发布 Calnio，实现 Notion 数据库与 iCloud/Apple Calendar 双向同步，解决现有 webcal 只读且刷新不可控的痛点。产品免费、自托管、正在寻求试用反馈；有明确使用场景和一定竞品空档，但尚未出现付费意愿或收入数据。
