WHAT’S ODK
• Open Data Kit (ODK) is a open-source suite of tools that allows data collection using
Android mobile devices and data submission to an online server, even without an
Internet connection or mobile carrier service at the time of data collection
• Developed by collaboration between researchers at the University of Washington in
Department of Computer Science and Engineering and active members of “Change”,
a multi-disciplinary group at UW exploring how technology can improve the lives of
under-served populations around the world.
