Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
ONE is a Biological Operating System powered by OPL® that interprets your health data and guides decisions for performance, recovery, and longevity.
Meet ONE — The Biological Operating System for Human Optimization.
ONE connects your bloodwork, biometrics, nutrition, and lifestyle data to interpret your biological state and guide smarter decisions for your health, performance, recovery, and longevity.
Powered by the OPL® Engine (Optimal Performance Line), ONE doesn’t just track your data — it understands what your body needs and tells you what to do next.
Instead of guessing, ONE helps you understand:
Why you feel tired
Why weight loss may be stalled
When to push performance
When to recover
What to change to improve your health
ONE acts as your Health Navigator, analyzing your data and guiding decisions across cardiometabolic health, cognitive performance, recovery, and physical performance.
