Healia - Privacy-first recovery score for Apple Watch

Healia turns the sleep, HRV, and resting heart rate your Apple Watch already collects into one daily recovery score — Good, Stable, or Poor — computed entirely on iPhone. No account, no server, no analytics — nothing leaves your phone. Free forever: daily score, today's detail view, Watch complication. Pro (one-time purchase, no subscription) adds weekly/monthly/yearly trends, any-date lookback, manual refresh, and weekly/monthly recovery reports. Built by a solo dev in Hong Kong.
