# Vital Health Scan

> Scan your face with your phone camera and read 300+ health biomarkers in about a minute, no wearable required. Powered by clinically validated rPPG (remote photoplethysmography).

Vital Health Scan turns any smartphone camera into a contactless health check. It reads the pulse in your skin with rPPG and reports heart rate, HRV, respiration and hundreds more wellness signals. No needle, no lab, no cuff. It is a wellness tool for tracking trends over time, not a medical device or a diagnosis.

## Who it is for

- People who want frequent, low friction health check-ins without a wearable.
- Affiliates and partners of Vital Health Global sharing the app with their audience.
- Anyone comparing camera-based (rPPG) vitals against the underlying science.

## How it works

1. Open the app and look into your phone camera in reasonable lighting.
2. Hold still for about a minute while the camera reads the blood volume pulse in your skin.
3. Review your biomarker report, labeled by evidence tier, and track it over time.

## Scan types

- **Face scan** (Front camera, rPPG) — flagship: The flagship. Look into your camera and read 100+ biomarkers from the pulse in your facial skin. No contact, about a minute.
- **Fingertip scan** (Rear camera and flash, contact PPG): Rest a fingertip on the rear camera for a higher precision pulse reading, plus blood oxygen and an atrial fibrillation check.
- **Palm scan** (Rear camera): Reads the blood flow in your palm and analyzes your nail beds as another route to your vitals.
- **Eye scan** (Front camera, pupillometry): Tracks subtle pupil and eyelid behavior for cues about fatigue, focus and cognitive load.
- **Voice scan** (Microphone): Analyzes the acoustic qualities of your voice for directional signals about stress, mood and breathing.
- **Motion scan** (Camera, motion amplification): Magnifies movement too small for the eye to see, surfacing signals like tremor and breathing patterns.

## Frequently asked questions

### How accurate is a face scan, really?

For heart rate, respiratory rate and HRV, camera-based rPPG has been validated against clinical references. Heart rate lands within roughly 1 bpm of an ECG in peer-reviewed studies, and respiratory rate reached 96% agreement in a 963 patient hospital trial. Other markers are shown as wellness insights or emerging research. See the Science page for citations.

### What do I need to take a scan?

Just your phone and reasonable lighting. Hold it at arm's length so your face is in frame, stay still for about a minute, and the app does the rest. No wearable, cuff or finger clip required.

### Is this a medical device or a diagnosis?

No. Vital Health Scan is a wellness tool for tracking trends over time. It does not diagnose, treat, cure or prevent any disease, and it is not a substitute for professional medical care. If something concerns you, talk to a clinician.

### What happens to my data?

Your scan is converted into biomarker readings, and you control what you keep and share. The app declares its data practices in the App Store and Google Play listings.

### Does it work across skin tones?

rPPG research increasingly spans diverse skin tones and lighting conditions, and validation studies have included varied populations. Accuracy can still vary with lighting and movement, and we are transparent about that on the Science page.
