EpiSurveyor allows anyone to very easily create a handheld data entry form, collect data, and then transfer the data back to a desktop or laptop for analysis. EpiSurveyor is one key part of a comprehensive technology partnership led by DataDyne with the support of the UN Foundation, the Vodafone Group Foundation, the WHO, the CDC, and Nokia. Our vision is to address the need for better public health data by providing sustainable and adaptable software tools to the developing countries themselves.
