I built a WHOOP-style recovery app that runs entirely on the iPhone — now in TestFlight

Solo dev here. apt turns Apple Watch data into Recovery, Sleep and biological-age scores, all computed on-device, with a “receipt” for every score so users can see exactly why. Stack: SwiftUI, HealthKit, optional Supabase account (off by default). The hardest part was making scores stable when Apple Watch HRV sampling is patchy. Would love feedback on onboarding and whether the value is clear in the first minute. https://testflight.apple.com/join/ZVHsNKy9 submitted by /u/Pur

AI 分析

痛点:Apple Watch 的 HRV 采样不稳定,市面上的恢复和睡眠评分黑箱不可解释,且数据要上传云端;用户想要本地计算、可解释的恢复分数。

目标用户:拥有 Apple Watch、关注训练恢复和生物年龄的健身爱好者和量化自我(Quantified Self)用户,原本可能订阅 WHOOP 或 Oura。

证据:“apt turns Apple Watch data into Recovery, Sleep and biological-age scores, all computed on-device, with a 'receipt' for every score so users can see exactly why.” / “The hardest part was making scores stable when Apple Watch HRV sampling is patchy.”

变现:采用免费基础分加订阅制(月度 3–5 美元或年度 20–30 美元),解锁趋势分析、生物年龄历史、教练导出和 Apple Health 深度集成;后续可做一次性买断的高级版。

MVP:用 SwiftUI + HealthKit 在 2 周内做出核心功能:读取 HRV、静息心率和睡眠数据,输出恢复分和睡眠分,并给出每个分数的“评分依据”明细页;不做账号和后端,只提供本地存储和一个简单趋势图。

竞品:WHOOP、Oura、Athlytic、Bevel、Welltory、StressWatch

摘要:一位独立开发者用 SwiftUI + HealthKit 开发了 apt,把 Apple Watch 数据在设备本地算成恢复分、睡眠分和生物年龄,并给每个分数附上“收据”式解释,目前在 TestFlight 测试。帖子本身没有披露任何付费意愿或收入数据,但 WHOOP/Oura 的订阅模式验证了该品类有付费市场;同时 Athlytic、Bevel 等竞品已经很多,差异化只能依靠本地隐私和分数可解释性。
