Yournumbers.Measuredagainstyou.
MyBodyAI learns how you usually sleep and what your resting heart rate usually is, and your HRV too if your device measures it. Every day it shows where you stand against yourself. From the same data it computes 12 health indices, biological age across 6 domains and Body Status, your daily state with a reason and what to do next.
Body Status
One state for today.
With the reason and the next step.
MyBodyAI reads 11 health indices plus Morning Energy, trends and patterns and picks one state: what is happening today and what to do about it. No abstract number, a concrete reason and a recommendation.
Every signal is read against your own normal from the last 7 and 30 days, not against a population average. After a month of wear, Body Status knows what is usual for you.
Energy Map
Your day,
hour by hour.
A personal curve of your energy across the day, modeled from your own sleep window and overnight recovery. It marks where you are right now, predicts your best window for hard effort and shows the dip after training.
Built per person from your data, not a generic chronotype chart. It is a model, not a live measurement, and it is labelled that way in the app.
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.
12 health indices
12 Indices. Every side of your health.
From recovery to cardiac fitness, from Body Alert to Body Clock: the whole picture of your health from your biometric data.
Body Alert
An index of how many of your biosignals are drifting from your personal normal at once. Not a diagnosis of any illness.
Immunity
Proxy markers (sleep, HRV, recovery) that correlate with immune function. Not a measurement of your immune system itself.
Recovery
How well your body recovered overnight, the foundation for everything else.
Stress Load
How much stress your body is carrying right now.
Sleep Debt
How many hours of sleep you owe, or have banked as a reserve.
Body Clock
How consistent your internal clock is day to day.
Nervous System
The "recovery" branch of your autonomic nervous system, read from your HRV. Not a measure of the balance of both branches.
Overtraining
Whether your body keeps up with recovery after training.
Breathing
How your breathing behaves during sleep and rest.
Cardiac Fitness
Aerobic-fitness indicator from resting heart rate and HRV. Not a measurement of myocardial efficiency.
Sleep Quality
How restorative last night actually was, not just how long.
Training Balance
How well your week is put together for health. NOT how much you trained.
Body Alert
See the change before you feel it.
Your body sends signals before you notice anything. MyBodyAI calibrates to your personal baseline and flags unusual biometric patterns that may mean your body is under strain.
HRV drop
May indicate increased autonomic nervous system load
Resting heart rate 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
+ breathing, skin temperature and morning energy, watched together.
Continuous monitoring
For informational purposes only. Not a medical device.
Biological Age
You are 28.
Your heart-rate readings
look like 24.
MyBodyAI reads your biometric history across 6 health domains: cardiovascular, body composition, sleep, autonomic nervous system, physical activity and VO2max. The result is an estimate from wearable data: which age your readings resemble. It is best read as a trend over months.
Each area is compared with the app’s own age bands, built on published reference data where it exists. You see which areas read younger or older than your years, and what to work on.
33+ peer-reviewed studies
Every algorithm in MyBodyAI is informed by published, peer-reviewed research. Where published tables exist, thresholds are adjusted for 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
Polar, Withings, Oura and COROS connect through the maker's account, Fitbit and Pixel Watch through your Google account, and the app pulls the history itself. Garmin connects directly through your Garmin account, and a data export fills in the older days.
Your data is scored
MyBodyAI processes biometrics, activity and sleep on its own, every night against your own baseline. The thresholds come from peer-reviewed research.
A briefing every morning
A daily briefing with recommendations built on your own patterns, not on population averages.
From numbers to a daily plan
The redesigned app reads your wearable and tells you what is happening today, why, and what to do about it.
Daily coach
Instead of a bare number, the Overview names your body's state in words and tells you whether today is for training, adapting or resting.
Energy map
See how your energy rises and falls through the day, find the best window to train or focus, and try a what-if before you commit to a bedtime or a workout.
Performance
Fitness, fatigue and form on a single curve, built from your training load, so you can see when to push and when to hold back.
Body load
A clear map of which parts of your body took the most load from recent activity, with the intensity and the workout behind it.
Health in depth
Body systems, biological age with its trend, and now vascular age, visceral fat and blood-pressure ranges from your Withings.
Progress
Daily rings, simple missions and a long-term journey that rewards consistency, not just genetics.
It learns from you
Scores are read against your own normal from the last 7 and 30 days, not against a table. The more nights we have, the better we know what is usual for you and what is a deviation.
Illness signature
The engine memorises the biometric fingerprint in the 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 7 days raises Body Alert regardless of starting level.
Training context
After hard training the engine expects elevated resting HR and suppressed HRV, thresholds relax automatically so you are not penalised for healthy adaptation.
Daily check-in
Reporting an illness raises Body Alert for that day. After 20 logged days, Trends shows which of your signals go with how you feel. The scores themselves do not change because of what you log.
Your own normal
A reading that is bad for everybody stays bad for you too. But a resting pulse of 62 means one thing for someone who usually sits at 55 and another for someone at 70: every reading is shifted by how far it sits from your own average.
