Kolibri - The offline app for universal education

Kolibri is a Learning Management System / Learning App designed to run on low-power devices, targeting the needs of learners and teachers in contexts with limited infrastructure. A user can install Kolibri and serve the app on a local network, without an internet connection. Kolibri installations can be linked to one another, so that user data and content can be shared. Users can create content for Kolibri and share it when there is network access to another Kolibri installation or the internet.
At its core, Kolibri is about serving educational content. A typical user (called a Learner) will log in to Kolibri to consume educational content (videos, documents, other multimedia) and test their understanding of the content by completing exercises and quizzes, with immediate feedback. A user’s activity will be tracked to offer individualized insight (like "next lesson" recommendations), and to allow user data to be synced across different installations -- thus a Kolibri learner can use his or her credentials on any linked Kolibri installation, for instance on different devices at a school.
