AI Vitals
Selfie. Sixty seconds. Vitals.
Nirogan uses remote photoplethysmography (rPPG) to extract clinical-grade vitals from a smartphone camera — no wearables, no contact, no fuss.
How rPPG works
Tiny color shifts your eye can't see, but math can.
Every heartbeat changes the volume of blood under your skin, causing micro-variations in skin color. A smartphone camera captures these signals at 30+ frames per second. Our models clean the signal, isolate the pulse, and translate it into vitals you can trust.
- Camera-only — no wearables required
- Works with standard front-facing cameras
- Designed for diverse skin tones and lighting
- Privacy-first: signals processed, faces never stored

What we measure
A complete vitals snapshot
More than just a pulse. A first look at cardiovascular, respiratory, and stress signals.
Heart rate
Beats per minute with high agreement vs pulse oximeter.
SpO₂ (estimated)
Peripheral oxygen saturation, in normal lighting conditions.
Respiratory rate
Breaths per minute via chest motion and pulse modulation.
HRV & stress
Heart rate variability as a proxy for autonomic stress.
Estimates intended for wellness and triage support. Not a substitute for clinical-grade devices in critical care.
Trust by design
Accurate, fair, and private
Validated against gold standards
Continuously benchmarked against clinical pulse oximeters and ECG, across diverse cohorts.
Designed for diverse users
Tested across skin tones, ages, and lighting. We publish our limitations openly.
Frames never leave your device by default
On-device processing where possible. Cloud paths are encrypted and consent-gated.
Where it shines
Built for real-world care
Whether at home, in a clinic, or across community camps — vitals just work.
Pre-consult triage
Patients scan before the consult; doctors see vitals before the call begins.
Chronic care monitoring
Daily checks for hypertension and cardiac patients — trends, not single readings.
Community health
Equip ASHA workers and camp volunteers with a vitals tool that needs no hardware.
