Our science
No black boxes. No made-up scores.
Every number in ExaHealth can be traced to a published model, a recognized clinical guideline, or your own baseline — and the app shows you which.

Methodology
From raw report to Health Score, in five steps
Collect
Lab reports, wearable vitals and medical imaging — gathered from photos, WhatsApp, Gmail, Apple Health and ABDM.
Analyze
Every value is mapped to evidence-based reference ranges from peer-reviewed studies and clinical guidelines.
Personalize
Ranges adjust for your age, sex, and life stage — pregnancy, menopause, senior health, chronic conditions.
Score
Each dimension is scored with clinically weighted markers — the most significant markers count the most.
Guide
Clear insights on what’s working and what needs attention — to discuss with your doctor, never to replace them.
The reasoning engine
Not a filing cabinet — a reasoning engine
It captures everything, reasons across your conditions, grades every finding and tells you what to monitor next — then hands you a report your doctor can read in a minute.
Captures everything
Every lab, vital, medicine and scan — one timeline
Lab reports, vital signs, medications, prescriptions and imaging are read and filed automatically — for you and every family member — so nothing is stranded in a WhatsApp thread or a drawer. No typing, no data entry.
- Labs · vitals · medications · imaging · wearables
- Auto-filed to the right family member
- Every value kept as a datapoint over time
Multi-condition reasoning
It manages conditions together — not in silos
Conditions are added from your medications, lab results and imaging, then reasoned about as a whole. High blood pressure on its own is a different picture once blood sugar joins it — so ExaHealth surfaces the related conditions to watch for, and marks the ones you’ve brought under control as Managed.
- Added from medications, labs & imaging
- Comorbidities analysed together, not one by one
- Related conditions to watch — and “Managed” ones flagged
Severity engine
Every finding graded — even from a scan
From a bloodwork flag to a 75% coronary stenosis inside an angiography report, each value is classified critical → normal against curated ranges. When it can’t classify a value safely, it says “no assessment” instead of guessing.
- Critical · high · borderline · normal tiers
- Labs, vitals and imaging findings
- Fails closed — honesty over coverage
Proactive monitoring
It tells you what to check next, and why
For every condition, ExaHealth knows which further tests and vitals to monitor and on what cadence — flagging what’s overdue to the day and grouping tests that can be drawn together. Proactive and guideline-based, not reactive.
- The exact tests & vitals to monitor per condition
- Overdue flagged to the day
- Batched into a single blood draw
A panel of estimates
Not one score — a panel of validated estimates
From the same labs, ExaHealth computes a set of science-backed estimates — each on a published research model, adjusted for your age, sex and conditions, with the exact markers driving it shown. Educational, never a diagnosis.
- Blood Sugar & Fat Balance — TyG insulin-resistance index
- Metabolic Syndrome — clustered cardiometabolic risk
- Liver Scarring Risk — FIB-4 fibrosis estimate
- Biological Age — PhenoAge over your bloodwork
Walk in prepared
One report your doctor can read in a minute
Everything the engine knows — captured, connected and consolidated onto one page you can print or share. So the few minutes you get with your doctor go to decisions, not to digging through old files.
- Lifestyle, vitals & the 30-day picture
- Active & Managed conditions
- Every abnormal lab, trended over dates
- Imaging & ECG findings
- Current medications & schedule
- Questions to ask — generated for you
- A guideline-based recommended care schedule

Vitals & wearables
The same rigor for your live signals
Heart-rate variability, sleep, stress and recovery — computed with research-grade methods, from your watch or your phone camera.
Readiness
RMSSD-based recovery with a signal-quality (SQI) score and drift from your own baseline — not a mystery number.
Sleep
Score, recovery and Deep/Core/REM/Awake stages read from a full hypnogram.
Stress & load
Autonomic strain via the Baevsky Stress Index, indexed to your 7-day baseline.
Camera HRV
Measure HRV straight from your phone camera when you don’t have a wearable.
…and every other vital, against your baseline
Published models
Built on research, shown working
HRV, the real way
RMSSD, SDNN, pNN50 and frequency-domain power (VLF/LF/HF) — the same metrics used in autonomic research, not a made-up wellness index.
Baevsky Stress Index
Our stress score is built on a validated measure of autonomic strain used in clinical and aerospace medicine for decades.
Biological age (PhenoAge)
Your biological-age estimate uses the published PhenoAge model over your actual blood biomarkers — every contributing marker shown.
Fail-closed severity
If we can’t classify a value safely — unknown unit, missing range — we say “no assessment” instead of guessing. Honesty over coverage.

Menopause
Adjusted ranges for hormonal transition, cardiovascular risk, bone density.
Senior health
Age-appropriate ranges, kidney function and cognitive markers.
Thyroid conditions
Condition-specific TSH targets and related marker adjustments.
Diabetes care
HbA1c targets, kidney surveillance, cardiovascular protection.
Heart conditions
