How It Works in the Field
A 30-second screening workflow designed for community health workers with minimal training — no equipment, no consumables, no connectivity required
Simple Steps to Get Started
Measuring your vitals takes less than a minute
CHW Opens Screening Mode
The community health worker opens the app during a household visit or campaign stop. Visual prompts guide positioning — hold the phone at arm's length facing the individual. Works in outdoor shade, indoor settings, and typical field lighting conditions.
30-Second Contactless Scan
The camera captures subtle skin color changes caused by blood flow. The individual simply faces the screen for 30 seconds — no contact, no discomfort, no infection control risk. On-device processing means the scan runs without any network connection.
Instant On-Device Results
Heart rate, HRV, SpO2 estimates, and stress indicators appear immediately on screen. Color-coded displays help CHWs identify individuals who may need facility referral. Results are stored locally and tagged with metadata for later sync.
Data Syncs to Health Systems
When the CHW reaches a connectivity point, queued screenings sync automatically to program dashboards and DHIS2. Supervisors see real-time coverage maps. District health teams get aggregate data without waiting for paper-based monthly reports.
