About Circadify
The team and rPPG technology turning any standard camera into a vital-signs sensor.
Making Vital Signs Accessible Through Any Camera
Circadify is building the future of contactless health monitoring. Our rPPG technology enables camera-based readings for heart rate, respiratory rate, HRV, and optional BP or SpO2 signals using a standard camera.
We believe that access to vital sign monitoring should not be limited by geography, income, or the availability of specialized hardware. By turning every camera into a health sensor, we are working to make healthcare more accessible and proactive.

Our Core Values
Accessibility
We believe vital sign monitoring should be accessible to everyone, everywhere, without expensive hardware.
Privacy First
Facial video data is never stored. We process in real-time and immediately discard all video frames.
Scientific Foundation
Our algorithms are built on published rPPG research and continuously improved through ongoing testing.
Innovation
We push the boundaries of what is possible with camera-based physiological measurement and AI.
Our Technology
rPPG Technology
Remote photoplethysmography detects subtle skin color changes caused by blood flow using standard cameras.
AI-Powered Analysis
Deep learning models read cardiovascular signals from camera data across diverse populations and conditions.
On-Device Preparation
The SDK handles capture guidance, quality checks, and measurement payload preparation locally.
HIPAA-Eligible
Enterprise privacy controls with encrypted transport and BAA support for qualified healthcare organizations.
Our biggest advantage is our data
Camera-based vital signs are only as good as their data. We built one of the most rigorous and representative datasets in the field, and it is what makes our measurements hold up outside the lab, on the phones people actually use.
Lab accuracy that holds up in the real world
Every participant is recorded at the same moment on lab-grade reference cameras and on ordinary iPhone and Android phones. Accuracy we prove in the lab carries over to the phone in someone's hand.
Measured against clinical ground truth
Readings are checked against medical reference instruments for heart rate, heart rate variability, blood pressure, oxygen saturation, and respiration, so every data point is anchored to a real clinical measurement.
Built for every skin tone
Our data spans the full Fitzpatrick I-VI range and deliberately over-samples darker skin, the blind spot that causes most camera-based vitals to fall apart outside the lab.
Owned, consented, and defensible
The dataset is proprietary, collected with consent for commercial use, and owned or exclusively licensed by Circadify. Competitors can't simply download or replicate it.
Validation from an independent research group
Circadify's performance is being evaluated by an independent, third-party clinical research organization. The results come from outside the company, so partners and investors don't have to take our word for it.
Results are expected in 2026, with a regulatory submission to follow. Circadify supports monitoring and screening, and is not intended for diagnosis.
