ODK Collect is powerful phone based replacement for your paper forms. Collect is built on the Android [8] platform and can collect a variety of form data types: text, location, photos, video, audio, and barcodes.
ODK Aggregate provides a ready to deploy online repository to store, view and export collected data. Aggregate is currently implemented on Google App Engine [10] and enables free hosting of data on Google's reliable infrastructure.
ODK Manage maintains a database of all phones in a deployment to enable remote device management. By sending an SMS to a deployed phone, Manage can trigger the transfers of forms, data, and applications.
ODK Validate ensures that you have a OpenRosa [13] complaint form -- one that will also work with all the ODK tools.
ODK Voice facilities mapping XForms to sound snippets that can be played over a "robo" call to any phone. Responses are collected using the phone's keypad (DTMF) and are automatically aggregated.
