Bio Optimizer - Built for what happens between your lab visits.

Bio Optimizer helps you see what happens between lab visits. Save blood panels, sync daily rhythm from Apple Health or Oura, and follow one private Optimizer Index on iPhone. Core scoring on device; optional iCloud—we don't warehouse your health data on our servers. Wellness education only, not medical advice. iOS 17+ · US App Store · feedback welcome.

Your Garmin gives you a recovery score every morning. Do you actually know what to do with it?

Mine says 68 today. Green zone apparently. But 68 out of what? Compared to what baseline? Why 68 and not 71? Should I train hard or take it easy? The app doesn't say. It just shows me the number and a vague color.

Most wearables give you a score with zero explanation of how they got there. Black box. Proprietary algorithm, tuned for some average user that probably isn't you. You either trust it or you don't, but you have no way to verify it either way.
