5-step assessment
Human OS Assessment
Complete the five steps. Cronometer, Whoop, metabolic cart RMR and NIX are optional. Manual entry always works.
Step 1 — Body & RMR
Safety & clinical protection
This app is educational decision support and not a medical or eating-disorder screening tool. If restrictive eating, low weight, dizziness, fainting, hormonal suppression or medical concern applies, guidance should be restore-first and professional support should be considered.
Step 2 — Activity Demand
Choose the single option that best reflects both physical movement and mental/cognitive strain. This combined demand sets the PAL energy multiplier and also informs movement/recovery routing.
Mental/cognitive load is built into the selected option, so there is no separate mental-load dropdown.
Capped at 10% to avoid extreme changes.
Minimum 4 weeks before reassessing.
Step 3 — Fixed 5-day Cronometer Input
Small upload option: fills the five most recent complete days and excludes today if it appears incomplete.
Advanced settings
Fat analysis is kept separate from traffic-light status. Around 15% fat is the Human OS gold standard; reductions in fat should replace calories with carbohydrate where needed.
Step 4 — Hydration Context
Uses energy and macros to estimate food water, glycogen water and metabolic water, then suggests the remaining drinking-fluid range. This is not a medical fluid prescription.
Step 5 — Biofeedback
These do not override the numbers, but they help place them in real physiology. Use 1 for very poor, 5 for neutral/average, and 10 for excellent.
Movement Guidance
