ODK

ODK is a free open-source suite of tools that allows data collection using Android mobile devices and data submission to an online server, without an internet connection or mobile carrier service at the time of data collection. ODK’s strength lies in its global community of developers and ease of adaptation and installation. Though it is being used for longitudinal client follow-up, it is primarily optimized for use cases that involve cross-sectional point-in-time data collection. Nafundi is the primary steward for ODK and supports the ongoing development. Since this is a platform that organizations regularly self-deploy, not all deployments can be documented. There are documented deployments in Honduras, India, Kenya, Niger, Nigeria, Philippines, South Sudan, Spain, Zimbabwe, and Somalia. There is an average of 400,000 users monthly who are actively using the application. The largest active project is in Honduras with 80,000 healthcare workers; the second largest is in Nigeria with 70,000 healthcare workers. With respect to COVID-19 applications, the largest project is in Somalia where 4,000 healthcare workers are submitting contact tracing data.
