NavigateHealth is currently a concept for developing a mHealth system to digitize the
HIV/health service mapping (facility and community based programs and pharmacy
services) and include crowdsourced feedback on service delivery. Community Health
Workers (CHW) will be able to access the system on an android based smartphone to
see where to send their clients for specific services, e.g. VCT, PMTCT, pharmacies,
household economic strengthening, etc.

• Contact information of service outlets provided
• Directions and time to selected service outlet sent to client via SMS
• Referral form sent to client to take to service delivery outlet via SMS
• Crowdsourced reviews of service outlets
