Sapelli is an open-source project that facilitates data collection across language or literacy barriers through highly configurable icon-driven user interfaces. We encourage people to download the app from the Google Play store, or from our GitHub repository and deploy it for their own purposes.

The sequence of interfaces that will be presented to the user in the project is described in the project’s XML file. The transmission of complete records is handled autonomously by the Sapelli platform, which periodically checks for connectivity and determines the most appropriate means by which to transmit the compressed data to another phone or a GeoKey web server.

This website should help to get started with creating bespoke data collection apps that meet individual requirements.
