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'

AI 分析

痛点:Notion 任务与 Apple Calendar 之间缺少真正的双向同步,现有工具只提供只读 webcal 订阅,用户需要手动维护两边。

目标用户:同时使用 Notion 管理任务、又依赖 Apple Calendar/iCloud 日历安排日程的个人用户和小团队。

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

变现:可做托管版订阅:按月收费提供稳定双向同步、冲突处理、多设备/多日历支持;也可提供一次性买断的自托管部署包或付费安装配置服务。

MVP:用 Notion API + iCloud CalDAV 实现双向同步核心:事件创建/修改/删除映射到 Notion 页面属性,提供冲突解决策略、同步日志和 Docker 一键部署,先不做复杂 UI。

竞品:Notion Calendar、Reclaim.ai、SyncThemCalendars、Zapier/IFTTT 自动化、CalendarBridge、Cron

摘要:一位独立开发者发布 Calnio,解决 Notion 与 Apple Calendar 只能单向只读同步的问题,支持事件双向创建、改名和日期变更,目前免费跑在自家 Raspberry Pi 上并在 Product Hunt 发布。帖子没有给出付费意愿或收入数据,但明确验证了 Notion+iCloud 双向同步的细分痛点,托管化订阅是潜在变现路径。
