The Engine Behind Contactless Vitals
Grounded in science
Rooted in the latest peer-reviewed rPPG research, developed with academic and clinical partners.
Learn moreReal-time processing on the user's device
Camera processing runs 100% on-device — no cloud dependency, private and precise in any conditions.
Learn moreAccuracy you can trust
Measured against established medical devices and supported by independent research.
Learn moreTrained on the highest-quality dataset
Built on our proprietary dataset, collected across the full range of skin types for accuracy that holds for everyone.
Learn moreCustom deployments
Take rPPG anywhere — automotive cabins, smart glasses, clinical kiosks, IoT and embedded cameras, even IR and thermal sensors.
Learn morePrivate by design
Raw video never leaves the device — only the derived vital signs are returned.
Learn moreBuilt for health and insurance leaders
Our remote photoplethysmography (rPPG) technology extracts vital signs from standard video in real time — heart rate, HRV, respiratory rate, blood pressure trends, and SpO2. Computer vision and AI read the biosignals entirely from an ordinary video feed, so there are no wearables or specialized hardware.

Your vital signs have been measured
Circadify drops into any product on any platform. Native iOS (Swift) and Android (Kotlin) SDKs, a Web SDK, and a REST API mean you can add contactless vitals to telehealth apps, kiosks, websites, or embedded devices without rebuilding your stack.
Benchmarked against gold-standard medical devices and engineered to hold accuracy across skin tones, lighting conditions, and device cameras. Circadify delivers consistent, dependable measurements in all real-world settings.
Getting started is fast. With pre-built components, our SDK can be implemented in under 10 minutes without rebuilding your existing experience. It runs on the cameras your users already have, so you can go from integration to live vitals the same day.
Web SDK
@circadify/web-sdk
Browser-based vital signs for JavaScript and TypeScript apps. Handles camera access, quality checks, secure upload, and result polling.
import { CircadifySDK } from '@circadify/web-sdk';
const circadify = new CircadifySDK({
apiKey: 'ck_live_your_key_here',
});
const result = await circadify.measureVitals({
videoElement: document.querySelector('video'),
});
iOS SDK
CircadifySDK
Native Swift package for iOS apps. Supports camera permission handling, measurement options, progress callbacks, quality warnings, and result retrieval.
import CircadifySDK
let circadify = try CircadifySDK(apiKey: "ck_live_your_key_here")
let vitals = try await circadify.measureVitals()
print(vitals.heartRate) // 72 BPMAndroid SDK
com.circadify:sdk
Native Kotlin library for Android apps. Handles camera permissions, measurement configuration, progress callbacks, quality warnings, and result retrieval.
import com.circadify.sdk.CircadifySDK
val circadify = CircadifySDK(apiKey = "ck_live_your_key_here")
val vitals = circadify.measureVitals()
println(vitals.heartRate) // 72 BPMBuilt for enterprise-level security and scale. Circadify is HIPAA compliant with end-to-end encryption and Business Associate Agreements, and it's backed by 99.9% uptime, sub-100ms response times, and 50+ existing integrations.

Private by Design
Raw Video Never Leaves the Device
All processing happens on-device. We extract regions of interest (ROI) locally and only process the signal data — raw video frames are never uploaded, transmitted, or accessible to anyone.
No Data Is Ever Stored
Results are returned in real time and never saved to any database. No video, no biometric templates, no personally identifiable data is retained — by us or anyone else.
You Control Your Results
Your measurements are yours alone. No one else can see your results unless you explicitly choose to share them.
Your Privacy is Protected
We take your privacy seriously. Here's how we protect your data:
Real Feedback From Real Users
Would Recommend to a Friend or Family Member
“I told my family about the app, and they were amazed at how the technology works and how quick the scan was.”
— Winnie, 24, Mother
Found the Scan Easy to Complete
“I just looked at my phone for a few seconds and it gave me my vitals. The people around me wanted to try it as well.”
— George, 28, Businessman
Believe It Could Improve Community Health Access
“Where I'm from, getting to a medical center for basic stuff requires a long wait. Something like this could change that.”
— Akunda, 26, Accountant
We Build the Model for Your Camera
Custom preprocessing algorithms, training pipelines, and rPPG models — built from scratch for your exact camera hardware and deployment environment.
Automotive Cabin Monitoring
We build custom preprocessing pipelines and train rPPG models specifically for in-cabin NIR and RGB cameras. Detect driver drowsiness, stress, and cardiac events in real time from dashboard and rearview mirror camera modules — even under rapidly changing ambient light, vibration, and partial occlusion.
- Custom models trained on NIR cabin camera feeds
- Drowsiness & cardiac event detection at the wheel
- Handles vibration, sun glare, and partial face occlusion
- Optimized for automotive-grade embedded processors

Frequently Asked Questions
Circadify uses rPPG technology to measure heart rate, respiratory rate, heart rate variability (HRV), blood pressure, SpO2, and stress — all from a standard camera in under 30 seconds, with no wearables or additional hardware required.
Circadify works with any device that has a standard camera - smartphones, tablets, laptops, and desktop computers. Our technology is platform-agnostic and can be integrated into existing telehealth platforms, EHR systems, and mobile applications. We also offer a native iOS app for direct consumer use.
You can start measuring vitals in minutes. For individual users, simply visit our demo page or download our iOS app. For enterprise integrations, our SDK can be implemented in as little as 10 minutes with pre-built components. Full EHR integrations typically take 2-4 weeks depending on the platform.
Yes, Circadify is fully HIPAA compliant. We use end-to-end encryption for all data transmission. Importantly, raw video never leaves the user's device - only extracted vital sign data is transmitted. We offer Business Associate Agreements (BAA) for healthcare organizations. All data processing can be done locally on-device for maximum privacy.
