# Presage Technologies - SmartSpectra SDK

> FDA-cleared contactless vital signs SDK that turns smartphone and webcam cameras into real-time biometric sensing inputs for apps. SmartSpectra Vital Signs Monitor 1.0 holds FDA 510(k) clearance (K254169) for heart rate and breathing rate on iOS and Android — and those cleared metrics are free for hospitals, clinics, health organizations, educators, and developers.

## FDA Clearance

- SmartSpectra Vital Signs Monitor 1.0 SDK received FDA 510(k) clearance, submission number K254169.
- Cleared indication: contactless pulse rate (heart rate) and breathing rate measurement on iOS and Android using a standard mobile device camera. No wearables, physical contact, or specialized hardware.
- Accuracy: 1.32 BPM RMSE for heart rate and 1.75 BrPM RMSE for breathing rate versus reference-standard equipment.
- Validation: peer-reviewed, published clinical trials at Baylor College of Medicine with 111 participants spanning all skin tones and diverse ages and BMI groups.
- The cleared metrics (heart rate and breathing rate) are free on iOS and Android for everyone: hospitals, clinics, global health organizations, educational institutions, and developers.
- Metrics beyond heart rate and breathing rate (e.g., HRV, blood pressure changes, facial expression analytics) are NOT part of the cleared indication and are intended for wellness and research use.
- For medical device manufacturers, SmartSpectra can serve as a cleared component within a broader device, accelerating their own 510(k) regulatory pathway.

## What is SmartSpectra?

SmartSpectra is a software SDK for contactless vital-sign sensing using smartphone and webcam cameras. A user faces the camera for about 30 seconds; the platform returns clinically validated vitals. Processing happens on-device; no facial images or video are stored or transmitted — only anonymized metrics are delivered to the host app.

## Measurements available

- Heart rate (pulse rate) — FDA cleared on iOS and Android
- Breathing rate (respiratory rate) — FDA cleared on iOS and Android
- Heart rate variability (HRV)
- Blood pressure changes (uncalibrated)
- Pulse waveform
- Breathing waveforms, apnea detection, inhale/exhale ratio
- Micro-expressions and facial action units
- Lip and speech activity
- Blink rate and eye tracking

Accuracy depends on lighting conditions and minimal motion during measurement.

## Platforms

- iOS (Swift) and Android (Kotlin) — the FDA-cleared configuration
- Cross-platform C++ on Linux, macOS, and Windows
- REST API / cloud integration for streaming anonymized metrics to apps or LLMs
