痛点：长途跨时区飞行后的时差调整缺少可执行、基于科学的昼夜节律计划，同时用户不愿把行程数据交给需要注册账号的云服务

目标用户：频繁跨时区出差或旅行的商务人士、长途飞行旅客

证据：I travel a lot, and jetlag was one of my main issues after my long flights. … Privacy was the main design goal: No account, no analytics, no cookies, no server. Your trip never leaves your device.

变现：免费开源作为获客入口，靠付费增值功能变现：多行程历史与提醒、可穿戴设备联动、家庭或团队差旅版订阅；B2B 方向可授权给航空公司、差旅管理公司（TMC）、企业差旅福利包

MVP：用两周做出 PWA：输入航班（出发/到达时间与经度）和日常作息，根据光照时窗和褪黑素时窗规则生成逐日相位图与睡眠/光照/咖啡因/小睡建议；纯前端计算、无账号、localStorage 存储、离线可用、导出 .ics；先不做账号与云同步

竞品：Timeshifter、Jet Lag Rooster、Entrain、JetLag 类 iOS 应用

摘要：作者因自身长途飞行受时差困扰，做了名为 Phase Jumper 的免费开源网页工具，输入航班与作息后生成逐日相位图，提示睡眠、光照、咖啡因、小睡、运动和褪黑素的时间窗口。产品强调隐私（无账号、无分析、无 Cookie、无服务器、行程数据不出设备）与离线可用，支持通过 URL fragment 分享计划和导出 ics。帖子本身没有收入或付费数据，属于免费开源发布，变现需靠增值订阅或企业差旅授权。
