How it Works
Contactless, Effortless - With Just a Camera
Our software uses existing cameras in smartphones and, really, any webcam to see the person or people the app is built for and starts to provide your application with real time information on that user within seconds of starting.
Here are the basics

Powering Up Your App.
Data Starts to Flow.
From healthcare to gaming, from automotive to wellness — our sensing layer adapts to any environment. Explore how leading industries use it, or spark ideas for your own.
SDK Integration: Powering Your App
Simple & Flexible – Integrate with just 10 lines of code
Embed the SDK
Integrate the lightweight SmartSpectra™ SDK into your iOS, Android, or cross-platform app.
Connect with the API
Your app sets itself up to make real-time API calls to activate the SDK, control the device camera (and/or microphone, if configured) and be ready to deliver measurements.
Configure Output
Choose what biometrics to access and with what frequency (see pricing):
- Heart Rate (HR)
- Facial Expressions / Stress
- Breathing Rate (BR)
- (Optional roadmap: EDA, SpO₂, HRV, blood pressure, etc.)
Run Your App
Simple & Seamless – No Wearables Required
User is seen by camera
Your app will activate the
- Front-facing or rear camera or
- Mounted or room-installed device
Real time analysis
SDK checks quality and analyzes the real time video of the user's upper body to extract physiological data using computer vision + signal processing
- Heart Rate (HR)
Data flows to your app
Data starts to flow within 3–5 seconds for most metrics
- Heart Rate (HR)
Create Digital Magic
You control the data - Powerful, Secure, Private
API Returns Data
Requested HR, BR, and emotion/stress signals are flowing to your app on the edge
- Heart Rate (HR)
Your app creates the magic
- Display data in-app to users (e.g., dashboards, real time traces, coaching)
- Send data to your backend or cloud- Integrate with EHR (for clinical or remote monitoring use cases)
- Export to analytics, AI models, or research

Why Choose Presage?
Answers to the frequently asked questions
Can I try this out for myself, on my own smartphone?
Absolutely, click on the CHECK IT OUT button at the top of this page.
Give us a little information so that we can give you access credentials, then we will give you the link to the Apple Store where you can get your free copy.
Yes, that easy.
Can my team do this?
Sure you can!
With automated coding tools like Claude Code and the pre-packaged features of the Presage SmartSpectrum SDK, your team can create a new application for a smartphone, webcam or integrated camera or add in new features to an existing application.
Have your team choose a platform for your users: Apple iOS, Google Android or Laptop-based C++ systems and we can get them templates and instructions to get a prototype going in an afternoon.
And, if you need the medical grade data to get securely back to your home electronic medical record or other systems, the highest security transmission protocols are readily available.
How can me team get the code to incorporate into my application?
Is it expensive?
Not at all.
We are designed to save you money.
Our costs start at $0.007 per measurement delivered to your application, so you can do the math.
How much does it cost in time and equipment to get a trained clinician to a person needing your service when all they have to do is open your app on their cell phone?
In less than the time than it takes to get a digital home thermometer to start giving you a reading, you can be getting real time, medical grade data streaming to you from your users.
That is time an efficiency savings at their best.
