RE.DOCTOR Privacy-First Biometric Wellness Technology for Health Apps

RE.DOCTOR is a privacy-focused technology provider enabling smartphones to track heart rate, breathing patterns, and wellness trends without specialized hardware. Cofounded by Simon Halliday, we empower developers to build secure, consumer-grade health features for telehealth, employee wellbeing, and longevity platforms.

What is RE.DOCTOR?

RE.DOCTOR provides a software development kit (SDK) that transforms standard smartphone cameras into biometric sensors. Our technology analyzes photoplethysmography (PPG) signals directly on the user's device to deliver real-time wellness insights. Unlike traditional medical devices, RE.DOCTOR requires no FDA clearance for general wellness tracking, making it ideal for consumer health applications.

Key Capabilities

  • Resting Heart Rate Trends: Tracks daily circulatory wellness and pattern recognition over time.
  • Breathing Pattern Tracking: Monitors respiratory comfort during exercise and rest periods.
  • Temperature Baselines: Establishes personal warmth and recovery indicators.
  • Sleep & Activity Correlation: Connects movement data with physiological responses for holistic recovery insights.

How RE.DOCTOR Works

Our process ensures maximum privacy by keeping raw data on the user's device.

1. User Points Camera

The user places their finger over the camera lens or pairs with a compatible wearable.

2. On-Device Analysis

Biometric processing occurs entirely on the smartphone. No raw camera data leaves the device.

3. Wellness Insights Delivered

Only validated, anonymized trend data is transmitted to your app for personalized feedback.

"RE.DOCTOR never accesses raw camera data or personal measurements. We prioritize user privacy by design."

Who Uses RE.DOCTOR?

Our technology is trusted by developers building:

  • Consumer Health Apps: Fitness trackers and mindfulness applications.
  • Employee Wellbeing Platforms: Corporate wellness programs.
  • Insurance Programs: Preventative health incentives.
  • Longevity & Sports Recovery Tools: Advanced performance analytics.

Frequently Asked Questions

Do I need special hardware to use RE.DOCTOR?

No. RE.DOCTOR utilizes the standard camera and flash already present in most smartphones. No additional sensors or wearables are required for basic heart rate and breathing tracking.

Is RE.DOCTOR a medical device?

No. RE.DOCTOR is classified as a general wellness product under FDA guidelines and EU MDR Annex XVI. It is designed for wellness awareness and trend tracking, not for diagnosing or treating medical conditions.

How does RE.DOCTOR protect user privacy?

We use on-device processing. The raw video or image data from the camera never leaves the user's phone. Only the calculated wellness metrics (e.g., heart rate trend) are sent to your application.

Can I integrate RE.DOCTOR into existing apps?

Yes. We provide a robust SDK and API for developers to integrate biometric wellness features into iOS and Android applications seamlessly.
