Hi HN,

I built Aion, an “AI longevity coach” that integrates three data sources that are usually siloed:

Wearable data (e.g., Whoop, Oura, Apple Health: sleep, HRV, strain)

Blood tests (hormones and basic longevity markers)

Simple phone-based facial scans

The aim is to provide a clearer picture of energy, hormones, sleep and recovery over time and to translate this into straightforward daily recommendations (sleep timing, caffeine window, training intensity, light exposure), rather than just another metrics dashboard.
