"The tracking feels accurate and consistent. Sleep, recovery, HRV — all the metrics I actually care about. And I'm not paying $150 a year just to read my own data."
Most people feel something is off long before their doctor finds anything. CirvioBody shows you exactly what it is.
How CirvioBody works
HRV, skin temperature and stress patterns — read continuously while you sleep, then turned into a single morning report that tells you exactly what changed and what to do about it.
Heart rate, HRV, temperature — mapped to your body over 14 days. Not population averages. Your baseline.
The moment something deviates from your normal — HRV, temperature, stress — CirvioBody flags it days before symptoms appear.
What changed overnight. What your body can handle today. What to do about it.
SIX AREAS. EVERY DAY.
Tap any area to see what CirvioBody tracks and what it tells you every morning.
01 Morning recovery score
Every morning you get a single score that tells you how recovered your body is and what it can handle today — before you make a single decision about training or workload.
02 HRV tracking
Heart Rate Variability is the most accurate measure of recovery available. CirvioBody Pro tracks yours continuously and shows you exactly when your nervous system is ready — and when it isn't.
03 Recovery trend analysis
See how your recovery has trended over the past 30 days. Identify patterns that explain why some weeks feel effortless and others feel impossible.
04 Strain vs recovery balance
CirvioBody Pro shows you whether your current lifestyle is building you up or breaking you down — in real numbers, not feelings.
05 Doctor-ready recovery data
Export 30 days of recovery data as a PDF. Walk into your appointment with longitudinal evidence — not just how you feel today.
01 Track your sleep stages
CirvioBody tracks light, deep, and REM sleep every night — each stage serves a different purpose in your recovery and shows you exactly what happened while you slept.
02 Understand your sleep need
CirvioBody calculates how much sleep your body actually needs based on your activity, stress load, and accumulated sleep debt — not a generic 8-hour recommendation.
03 Optimize your sleep performance
Quality matters as much as quantity. CirvioBody monitors your efficiency, wake events, and deep sleep percentage to show you exactly where your nights are breaking down.
04 Build your sleep schedule
See which bedtime and wake time combination consistently produces your best recovery scores — then stick to it.
05 View your sleep trends
Track your sleep performance over weeks and months to identify patterns, spot what's hurting your sleep, and show your doctor 30 days of data at once.
01 Daily stress score
A 0-100 score calculated from HRV every morning — updated before you even get out of bed, before you feel anything is wrong.
02 Stress pattern detection
CirvioBody Pro shows you which specific days, habits, and situations consistently push your nervous system into strain territory.
03 Early burnout warning
When your stress accumulates faster than your recovery, CirvioBody Pro flags it days before you hit the wall — so you can act before you crash.
04 Guided recovery
On high-stress days, CirvioBody Pro shows you exactly what your body needs to recover — and how long it will take.
05 30-day stress report
Export a complete picture of your stress patterns. Show your doctor not just that you're stressed — but exactly when, how often, and how severely.
01 Continuous heart rate tracking
CirvioBody Pro samples your heart rate continuously, 24/7 — not every few minutes like most trackers. The signals that matter most often appear between the checks.
02 HRV monitoring
HRV is your body's most sensitive early warning system. CirvioBody Pro tracks it every night and flags when your autonomic nervous system is under strain.
03 Irregular rhythm detection
CirvioBody Pro monitors for irregular heart rate patterns and flags anomalies that may warrant medical attention — days before you feel anything.
04 Resting heart rate trends
Your resting heart rate tells a story about your cardiovascular health over time. CirvioBody Pro tracks it daily and shows you whether your heart health is improving.
05 Blood oxygen monitoring
SpO2 monitoring tracks your blood oxygen saturation continuously — flagging drops that can indicate illness, poor recovery, or respiratory issues.
01 Skin temperature tracking
±0.2°C accuracy detects the subtle temperature shifts that happen days before illness, hormonal changes, or burnout become obvious. Precise enough to show a pattern, not just a number.
02 Blood oxygen monitoring
Continuous SpO2 tracking flags drops in blood oxygen that can indicate illness, poor sleep quality, or respiratory issues before you notice any symptoms.
03 Blood glucose risk assessment
The BGEM algorithm monitors blood glucose risk patterns from your skin — no needles, no test strips. An early warning system for one of the most common undetected health conditions in the world.
04 Fitness Age
CirvioBody Pro calculates your biological age daily — not your birth age, but how old your body actually is based on your real health data. See if your habits are making you younger or older.
05 Women's health tracking
Period prediction, ovulation tracking, and pregnancy health monitoring — all built in. CirvioBody Pro tracks the hormonal patterns that affect energy, sleep, and recovery throughout your cycle.
01 VO2 Max monitoring
CirvioBody Pro calculates your VO2 Max — the gold standard measure of cardiovascular fitness — and tracks how it changes as your training improves.
02 54 auto-detected sports
CirvioBody Pro automatically recognizes your workout within 3 seconds — running, cycling, swimming, HIIT, and 50 more. No manual logging required.
03 Daily activity tracking
Steps, calories, and active minutes tracked automatically — with context about how your daily activity is affecting your recovery and long-term health.
04 Training readiness score
Before every workout, CirvioBody Pro tells you exactly how much your body can handle today — so you push when you should push and rest when you should rest.
05 Long-term performance trends
Track your VO2 Max, activity levels, and fitness age over months and years. See in real numbers whether your training is making you fitter — or just keeping you busy.
Your heart rhythm changes days before you feel exhausted. CirvioBody tracks Heart Rate, HRV, Stress Score, and VO₂ Max continuously — so you see the pattern before it becomes a problem.
Not all sleep is recovery. CirvioBody breaks down Deep, REM, and Light stages, calculates your Sleep Debt, and gives you a Recovery Score every morning — so you know what your body can actually handle today.
Skin temperature accurate to ±0.2°C, SpO₂, Biological Age, and Cycle Tracking — measured continuously, exportable as a 30-day PDF report. Real data to bring to any appointment.

See if you're aging faster or slower than calendar age. Watch it improve as sleep, stress, and recovery optimize.

Track deep, REM, and light sleep stages. Know if you're getting restorative rest or just lying in bed.
