Data that actually matters
Not another step counter. The metrics cardiologists and longevity researchers use, translated into a dashboard you can understand.
Accurate biological age
Wisløff & Nes formula (2014) — validated on 55,000+ subjects. VO2max + HRV + RHR tell you how well your body is aging.
Healthspan Score 0-100
A single number that shows your trajectory. Breakdown across 6 components — see what works and what needs adjusting.
6 longevity habits
Sleep, strength, Zone 2, eating window, morning light, thermal exposure. Check off daily, see weekly consistency.
Personalized insights
AI identifies your top 3 weak points and tells you what to change this week — concrete, not generic.

Based on published research
No hyped promises. The formulas and thresholds come from medical literature — transparently cited.
Wisløff & Nes 2014 — Fitness Age model, validated on 55,000 Norwegian adults. Better predictor than chronological age for cardiovascular mortality.
Lee et al. 2019 (JAMA) — 7,500 steps/day reduces mortality by 50% vs under 4,000. Step consistency matters more than intensity.
Nunan et al. 2010 — meta-analysis of age-adjusted HRV norms. SDNN below age-median correlates with elevated cardiovascular risk.
