Optical biometrics · On-device AI

Your selfie is now a health checkup.

Look at your phone for 30 seconds. SENTIO reads your vitals and a full panel of biomarker estimates from light reflected off your skin. No wearables. No needles. Nothing uploaded.

20 readings, one scan 100% on-device Any iPhone camera
How it works

Scan. Analyze. Know.

Every heartbeat subtly changes the color of your skin. SENTIO's camera AI reads those changes, then cross-checks every result before showing it to you.

01 · SCAN

30-second face scan

Choose Face, or Dual (face plus fingertip). Live coaching flags low light or motion so every scan counts.

02 · ANALYZE

Computed on your phone

Signal processing and AI models run on the phone's neural engine. Video is analyzed in memory and never leaves the device.

Results by health area

Vitals, biomarker estimates and signal quality, compared with your own baseline. Save to your health record in one tap.

What it measures

Vitals and biomarkers.
One camera.

Six health areas from a single scan. Each reading is labeled so you always know what was measured and what was estimated.

Heart rate

Measured

Beat-to-beat pulse from the facial blood volume signal.

Heart rate variability

Measured

RMSSD, a marker of recovery and stress balance.

Blood pressure

Estimate

Systolic and diastolic estimate from pulse wave features.

Optical ECG

Estimate

Live waveform view of rhythm and HRV.

Respiratory rate

Estimate

Breaths per minute from subtle chest and face motion.

Oxygenation (SpO₂)

Estimate

Blood oxygen estimate from multi-wavelength light response.

Hemoglobin & hematocrit

Estimate

Indicators related to oxygen-carrying capacity.

Glucose & HbA1c index

Estimate

Optical indices related to blood sugar trends.

Lipid vascular index

Estimate

Optical index related to cholesterol and triglycerides.

Hepatic & uric acid index

Estimate

Optical indices related to liver and metabolic markers.

Hydration & edema

Estimate

Fluid balance indicators from skin and facial features.

Temperature

Estimate

Body temperature estimate, or enter your own reading.

Eyes

Estimate

Pupil and eye measurements captured during the scan.

Face & skin

Calculated

A skin health score calculated from facial features.

Body composition

Estimate

Body fat and lean mass estimates.

Voice & hand steadiness

Coming soon

Vocal and motion sensor signals, ready to switch on.

Estimates are wellness indicators, not lab results. Readings vary with lighting, motion and skin tone conditions; SENTIO reports signal quality with every scan.

Why SENTIO

No hardware. No cloud. No friction.

Just the phone they own

No cuffs, straps or proprietary sensors to ship, charge or replace. Pair Apple Watch or a Bluetooth cuff when you want more.

Private by architecture

Your face never leaves your phone. No video server, no cloud processing, and results are shared only when you choose.

Built for real life

Real-time coaching for light and motion, a consensus check on every signal, and one-tap saving to the health record.

Where it fits

Health checks between visits.

A simple daily check-in that people actually do, wherever they are.

HEALTH PLANS

Medicare Advantage

Member engagement, retention and support for Star Ratings programs.

POST-ACUTE

Rehab centers

Stay connected with inpatient and outpatient rehab patients after discharge.

CLINICIANS

Practices & telehealth

A vitals snapshot before every virtual visit, no device kit needed.

AT HOME

Seniors & families

Check on yourself, or a parent, with profiles for the whole household.

Evidence

Tested against people,
not just devices.

0

Comparison sessions

Respiratory rate compared with manual counts by trained observers.

2

All processing happens on the device.

Ask ZEAN

Health answers that stay yours.

An on-device assistant that explains your results and answers health questions. It does not track or store what you ask.

My HRV dropped this week. Should I worry?
HRV often dips with poor sleep, stress or illness. Compared with your baseline, this is a modest change. If it stays low or you feel unwell, check in with your doctor.
