KnowYourBodyLikeNeverBefore.
MyBodyAI turns your wearable data into 12 AI-driven health indices, biological age across 8 domains and early detection of unusual health patterns. Body Status — your daily health state with a clear reason and what to do next.
Body Status
Not a Number.
Context & Action.
MyBodyAI analyzes all 12 health indices, trends and patterns to determine one dominant state — what is happening today and what to do about it. No abstract number. Concrete reason and recommendation.
Your profile is built from your own data — not population averages. The longer you track, the more accurate your Body Status becomes.
Training Readiness
How much can you handle today?
Training Readiness measures your current capacity for physical effort. Five components — from recovery to stress load — combine every morning into a single score across three clear zones.
Sleep debt above 2 hours automatically pulls your score down. It answers a simple question: how hard can I push today?
Body Status tells you how you are. Training Readiness tells you what you can do.
Health Intelligence
12 Indices. Every Dimension of Health.
From recovery to biological age, pattern detection to circadian rhythm — complete health intelligence from your biometric data.
Body Status
AI-driven daily health state — context, reason and action instead of a number.
Illness Risk
AI monitors for unusual biometric patterns that may indicate your body is under stress.
Biological Age
How old your body really is — across 8 health domains.
Immunity
Immune system strength from HRV, sleep and recovery patterns.
Recovery
How recovered your body is — ready for activity or still resting.
Stress Load
Cumulative physiological stress from HRV and body battery patterns.
Sleep Debt
Cumulative sleep deficit against your personal optimal duration.
Circadian Rhythm
Sleep-wake timing consistency — a key longevity predictor.
Autonomic Balance
Balance between your "fight-or-flight" and "rest-and-digest" nervous systems.
Overtraining Risk
Acute-to-chronic workload ratio — prevents injury and burnout.
Respiratory Health
Breathing patterns and nocturnal SpO2 — early signal for respiratory issues.
Cardiac Efficiency
How efficiently your heart works at rest — RHR trends and heart rate reserve.
Morning Energy
Body Battery level at wake-up — how much energy you recovered overnight.
Sleep Quality
Sleep architecture — efficiency, phase balance and deep sleep adequacy.
Key Feature
Early Warning System.
Your body sends signals long before you notice anything. Our AI learns from your personal data over time and detects unusual biometric patterns that may indicate your body is under stress.
HRV drop
May indicate increased autonomic nervous system load
Resting HR rise
Observed increase above your personal resting baseline
Sleep fragmentation
More frequent awakenings and shallower sleep stages
SpO2 variance
Greater oxygen saturation fluctuation compared to your usual range
+ dozens more biometric patterns monitored simultaneously.
Signals monitored continuously
For informational purposes only. Not a medical device.
Biological Age
You are 28.
Your cardiovascular
age is 24.
We analyze years of your biometric data across 8 health domains — Cardiovascular, Body Composition, Recovery, Sleep, Stress Resilience, Autonomic Nervous System, Physical Activity and VO2max. The result is your true biological age, not your calendar age.
Each domain trains on your own longitudinal data. See exactly which areas you are biologically younger — and which to target.
32+ peer-reviewed studies
Every algorithm in MyBodyAI is grounded in published research. All thresholds are stratified by age and sex.
MyBodyAI is not a medical device. It provides wellness analytics from wearable data for informational purposes. Consult a healthcare professional for medical concerns.
How It Works
Up and running in 3 steps
Connect your wearable
Link Polar, Strava, Withings, Fitbit in one click. No manual setup needed.
We analyze your data
Our AI engine processes biometrics, activity and sleep automatically. Models trained on 5+ years of longitudinal data.

Daily health briefing with actionable recommendations tailored to your unique patterns — not population averages.
It learns from you
The longer you use MyBodyAI, the more accurate it becomes. Every day of data improves accuracy of pattern detection, calibrates scores, and builds your personal health model.
Personal Illness Signature
The engine memorises the biometric fingerprint 3–7 days before each illness. When the current pattern matches a past signature, alerts fire earlier and with higher confidence.
HRV Velocity
It is not just the absolute HRV value — it is how fast it drops. A fall >3 ms/day over 3 days raises illness risk regardless of starting level.
Activity Context
After hard training the engine expects elevated resting HR and suppressed HRV — thresholds relax automatically so you are not penalised for healthy adaptation.
Self-Report Calibration
Daily 'how do you feel?' entries calibrate the algorithm. After 30 entries, Body Status weights shift toward the metrics that best understand your energy patterns.
Personal Percentile Scoring
You are scored against your own history. Hybrid: 70% your distribution + 30% population norm — rewards progress, not just genetics.
Recovery Debt
A new 0–100 metric tracking cumulative recovery deficit from training, sleep and stress. Distinct from sleep debt — reflects total physical fatigue.
