A Flutter mobile application that uses facial scanning and computer vision to estimate heart rate, SpO₂, blood pressure, breathing rate, and stress levels — all from a smartphone camera, with no wearables required.
Reactive Heart represents a paradigm shift in personal health monitoring. Built entirely in-house by StrongMoments Technologies, this mobile application leverages advanced computer vision, machine learning, and real-time signal processing to estimate a user's vital signs through nothing more than a smartphone's front-facing camera.
By analyzing subtle color variations in facial skin caused by blood flow (photoplethysmography via camera), the app extracts heart rate, blood oxygen saturation, blood pressure estimates, breathing rate, and computes a composite stress score — all in under 30 seconds. The backend uses a WebSocket-based pipeline for real-time frame processing and AI-powered ethnicity analysis to improve measurement accuracy across diverse populations.
Real-time face detection using Google ML Kit with validation for proper positioning, lighting, and stillness. Animated scan overlay provides live feedback during measurement.
Heart rate (BPM), blood oxygen (SpO₂), blood pressure estimation, breathing rate, and composite stress score — all derived from facial video analysis.
Camera frames stream to the FastAPI backend via WebSocket for server-side ML processing, returning rolling vitals updates every 5 seconds during scan.
An async ML job analyzes the first captured frame to determine ethnicity, allowing PPG algorithms to auto-calibrate for improved accuracy across diverse skin tones.
Upload photos of lab reports, X-rays, or prescriptions and get structured AI-powered medical analysis with findings, severity assessment, and recommendations.
All results are saved with timestamps and trend charts. Users can generate shareable PDF reports and track their health metrics over time.
Built-in pedometer with GPS-tracked walking routes and daily step goals to encourage an active lifestyle alongside vitals monitoring.
Configurable reminders for medication, water intake, and regular health check scans to build consistent health monitoring habits.
Full internationalization with Slang — currently supporting English and Hindi with extensible architecture for additional languages.
Reactive Heart proves that accessible healthcare technology doesn't have to be complicated. We've put clinical-grade vital signs monitoring into everyone's pocket — no extra hardware needed, just your phone's camera and our AI.— Engineering Team, StrongMoments Technologies
