I got tired of the pain under my shoulder blade from sitting all day, so I built an app that won't let me scroll until I stretch

AI 分析

痛点：久坐办公和学习导致肩胛内侧持续疼痛，用户明知该拉伸却总跳过提醒，因为普通提醒太容易被划掉。

目标用户：每天久坐 6 小时以上的 iPhone 上班族、学生和远程工作者，尤其是已有颈肩腰背劳损、想靠拉伸缓解症状的人

证据：hours of studying and working at a desk gave me a constant pain under my shoulder blade (the rhomboid). I knew stretching would help. I just never did it. Reminders were easy to ignore. Instagram was not. / To unlock them, you hold a stretch in front of the camera, and a timer counts down only if actually you hold it. / There's a 7-day free trial if you want to try it

变现：订阅制（月付约 $3-5、年付约 $20-30，7 天免费试用），可叠加拉伸课程包内购或一次性买断；后续可走企业健康福利（B2B 批量授权）渠道

MVP：用 Screen Time API 做应用锁，解锁前必须先完成 30 秒计时拉伸（先用前置摄像头加 Core ML 轻量姿态判断，或退化为纯倒计时加自拍确认），内置 10-12 个颈肩背动作和 2 个固定流程，提供 7 天试用和订阅，2 周内可上架

竞品：StretchMinder、Wakeout、Stand Up! The Work Break Timer、One Sec、Opal、ScreenZen

摘要：独立开发者因久坐导致肩胛内侧疼痛，做了 Kinetly：用 Apple Screen Time API 锁定分心 App，必须对着摄像头保持拉伸姿势并完成计时才能解锁，内置 31 个颈肩背髋腿动作，已上架 App Store 并提供 7 天免费试用。作者在帖子中只说想要反馈（'Does "lock your apps until you stretch" sound motivating to you, or just annoying?'），没有公布收入或订阅转化数据，付费意愿并未被验证，因此只能作为需求方向的弱信号。
