ODK Build is a web-based, drag-and-drop service for creating forms used with data collection tools such as ODK Collect and ODK Central. ODK Build is part of ODK, a free and open-source set of tools which help organizations author, field, and manage mobile data collection solutions. Learn more about the ODK project and its history here and read about example ODK deployments here.

If you want to build forms while offline, Build offers an offline version.
