About Circadify
We build the rPPG SDK and Vitals API that health platform teams use to ship contactless vital-sign features. Learn about the engineering team behind Circadify and why we are focused on making camera-based vitals infrastructure accessible to every developer.
Our Story
We started Circadify because the signal-processing pipeline for camera-based vitals was too hard for most engineering teams to build and maintain. The underlying science of remote photoplethysmography has been validated in research for over a decade, but turning papers into production-grade software that works across thousands of device and lighting combinations required deep specialization that most health platforms could not justify staffing.
Our team of computer vision engineers, embedded ML specialists, and developer-tools veterans packaged that expertise into a drop-in SDK. We handle face detection, signal extraction, noise filtering, and on-device model inference so that a single integration gives your app real-time heart rate, HRV, respiratory rate, stress index, and SpO2 output.
Today the Circadify SDK powers vitals features inside telehealth platforms, insurance applications, corporate wellness programs, and consumer health apps. Our focus remains the same: give engineering teams a fast, reliable, and privacy-respecting way to add contactless vitals to any product.
Our Mission
To make contactless vital-sign measurement available to every developer building health technology. We believe the infrastructure layer should be solved once so thousands of teams can focus on the products that improve patient and consumer outcomes.
What We Stand For
Developer Experience First
Clean APIs, typed interfaces, zero transitive dependencies, and sample projects that compile on first clone. We measure success by your integration speed.
On-Device by Default
All biometric inference runs locally. We do not see, store, or process your users' health data. This architecture simplifies compliance and builds user trust.
Platform Parity
iOS, Android, and Web SDKs share the same interface contract and output schema. Your team writes one integration pattern and ships to every surface.
Continuous Improvement
Our ML pipeline retrains on new device profiles and lighting conditions. SDK updates ship through standard package managers with semantic versioning and migration guides.
