Project Overview

It is an app for universities that allows students to learn online on mobile devices. The App's purpose is to provide students with all kinds of learning materials both online and offline: lectures, quizzes, questionnaires, etc.

Initially, this project was implemented on UIKit + MVC UI layer approach, and the app was delivered under "Mobile Campus" app. Access is restricted to university students only, and the main idea was to help them access class study materials. Later ported to the GetSmarted project.

The most complex part was class functionality implementation which allowed students to view content and answer exam questions. This required a lot of work with video and raw HTML data, complex API calls, syncing data offline, etc.
