Built differently

Most apps track. We interpret.

Whoop tells you your HRV. We tell you why it dropped, which biomarker is responsible, and what your protocol should change tomorrow.

  • Codex map. Every system in your body, scored and color-coded across hormones, cardio, metabolism, immune, gut, brain, detox, sleep, and stress.
  • 7 expert specialists. Talk to a hormone doctor, a peptide expert, a longevity physician — independently, on-demand.
  • Wearables that matter. Apple Health, Whoop, Oura, Garmin — synced, normalized, interpreted alongside your labs.
  • Daily routine. Personalized morning, midday, evening, and weekly schedules — generated from your protocol, not a template.
