The Ecosystem
Six systems.
One brain.
Every part of FITOS talks to every other part. Your training informs your macros. Your sleep adjusts your coach. Your bloodwork shapes your plan.
Training
AI-generated plans that progress with you, structured per-set logging, and estimated 1RM trends.
Nutrition
Adaptive macros from your weight trend, barcode scanner, meal logging, recipes.
AI Coach
Voice-first conversational coach with a fully customizable avatar that learns you.
Bloodwork AI
Upload labs. Get nutrition, supplement, and training suggestions across 30+ biomarkers.
Body Scan
A four-photo body scan with an AI composition estimate you can track over time.
Recovery
HRV, sleep, readiness, and stress — synced from your wearable, in one place.
Macros that learn your metabolism.
FITOS learns your real maintenance calories from your logged intake and your smoothed weight trend, then recalculates your targets each week. Needs consistent logging — and it tells you when it doesn't have enough.
Bloodwork, decoded.
Upload your labs in PDF or image. FITOS parses 30+ biomarkers — testosterone, thyroid, lipids, inflammation, micronutrients — and surfaces nutrition, supplement, and training suggestions.
Encrypted end-to-end. Your labs are yours, never sold, deletable anytime.
FITOS provides educational insights, not medical advice. Always consult your physician.
