Features Built for Community Health Delivery
Every capability has been designed for the realities of field deployment in Sub-Saharan Africa — low-cost handsets, intermittent connectivity, variable lighting, limited training time, and the need to screen large populations with zero specialized equipment. These are not laboratory features adapted for the field. They were built for the field from the start.
Core Vital Signs Screening
Camera-based health indicators captured in 30 seconds with no equipment
Heart Rate Estimation
Estimates resting heart rate from facial blood flow patterns detected by the smartphone camera using rPPG signal processing, providing a cardiovascular indicator without a pulse oximeter or chest strap
Heart Rate Variability (HRV)
Derives HRV metrics from inter-beat interval analysis, offering a window into autonomic nervous system function that can flag physiological stress during community screening
Stress and Recovery Indicators
Combines HRV patterns with sympathetic/parasympathetic balance estimates to surface stress-level indicators relevant to maternal health, NCD risk, and general wellness screening
Respiratory Rate Estimation
Detects breathing-related signal modulations in the rPPG waveform to estimate respiratory rate, adding a critical vital sign to the screening panel without additional sensors
Core Vital Signs Screening
Field Deployment Capabilities
Designed for real-world conditions in low-resource settings
Offline-First Architecture
Full screening functionality with no internet connection required. Data stores locally on-device and syncs automatically when connectivity resumes — essential for rural and peri-urban deployments
Low-Cost Device Compatibility
Optimized to run on entry-level Android smartphones commonly used by community health worker programs, with no requirement for high-end processors or cameras
Guided Scan Workflow for CHWs
Step-by-step on-screen instructions guide community health workers through each scan, reducing training requirements and ensuring consistent data capture across teams and districts
