Install the Open edX mobile app in a staging setup and complete part of a real course on the phones and network conditions learners use. Check video, reading, quizzes, progress sync, and what remains available when connectivity drops. Include accessibility settings and small screens.
A mobile app can improve reach only if course authors design for it. Check which course components behave differently from the web and document a fallback path. Do not judge the experience from login and a course list alone.
