Community Health Screening for Sub-Saharan Africa
Deploy vital signs screening across community health programs using the smartphones your CHWs already carry. No blood pressure cuffs, no pulse oximeters, no supply chain.
Why Choose Us
Advanced rPPG technology that transforms any camera into a health monitoring device
Zero-Equipment Vital Signs Capture
Circadify uses the front-facing camera on any Android or iOS smartphone to estimate heart rate, respiratory rate, and stress indicators through remote photoplethysmography (rPPG). No cuffs, probes, or consumables to procure, ship, calibrate, or replace. This eliminates the single largest barrier to routine vital signs screening in low-resource settings where supply chains are fragile and equipment budgets are limited.
Offline-First Field Operation
Community health workers operate in areas where mobile connectivity is intermittent or absent. Circadify processes all vital signs data on-device without requiring an internet connection. Screening results are stored locally and sync automatically when connectivity resumes, ensuring no data is lost between village visits and health facility reporting cycles.
CHW Training in Under One Hour
Complex diagnostic equipment demands weeks of training and ongoing calibration support. Circadify's camera-based workflow requires minimal instruction — community health workers can begin screening after a single training session. The intuitive interface guides each scan step by step, reducing supervisory burden and enabling rapid scale-up across new districts and regions.
Maternal and Neonatal Screening
Routine vital signs monitoring during antenatal visits and postnatal follow-ups can surface early warning signs that prompt timely referrals. Circadify enables CHWs to capture maternal heart rate and stress indicators at every household visit without additional equipment, supporting community-level maternal health surveillance in regions where facility-based care is hours away.
On-Device Data Privacy
All biometric processing happens entirely on the smartphone. No facial images, video frames, or raw biometric signals leave the device. Only derived vital signs estimates are available for export or sync, ensuring compliance with data sovereignty requirements and protecting the personal health information of vulnerable populations in program settings.
Sustainable Program Economics
Traditional vital signs equipment requires recurring costs for replacement parts, batteries, calibration, and logistics. A smartphone-only screening tool converts a sunk cost — the phone CHWs already carry — into a multi-purpose health instrument. This dramatically lowers per-screening cost and makes large-scale population screening economically viable for donor-funded and ministry-funded programs alike.
Built for the Last Mile
Circadify was field-tested in Uganda with community health workers conducting household visits in rural districts. The technology is designed for real-world conditions — variable lighting, low-cost handsets, intermittent connectivity — not controlled laboratory environments. We partner with NGOs and health ministries to integrate smartphone screening into existing community health programs.

Smartphone-based screening integrated into community health delivery models across Sub-Saharan Africa
Community-Based Screening Campaigns
Equip community health workers with smartphone-based vital signs capture for household visits and village health days. Circadify enables routine screening at the community level without waiting for patients to reach overburdened health facilities.
Zero-equipment field screeningAntenatal and Postnatal Monitoring
Support maternal health programs by adding vital signs screening to every CHW household visit during pregnancy and the postpartum period. Early detection of elevated heart rate or stress indicators can prompt timely referrals to facility-based care.
