This topic answers questions about how you can use the edX mobile app on an Android smartphone or an iPhone to take edX courses.
You can use the app to download course videos so that you can watch them whenever you want to, even without an Internet connection. When you have an Internet connection, you can also read course announcements, participate in course discussions, and get started on homework and other assignments. To complete an entire course, you use a web browser on a computer.
The answer depends on the types of problems that are used in the course you are taking. If a course contains mobile friendly problem types, you can complete those types of problems using the mobile app. For a list of the types of problems you can complete using the mobile app, see What types of problems can I do in the mobile app? You cannot take timed exams or proctored exams using the mobile app.
You can watch course videos on the mobile app, and can also download videos to your mobile device for watching when you do not have an internet connection. When you have an internet connection, you can also read course announcements, participate in course discussions, and complete the mobile friendly problems in your assignments.
To complete an entire course, you can use a web browser on a computer.
You can use the edX mobile app to do some, but not all, of the problems in your assignments. EdX courses include a variety of problem types. Currently, you can read questions and submit answers only for problem types that require relatively simple actions as responses.
For example, you can use the edX app to answer multiple choice questions, but you cannot use it to draw molecules or design circuits. To complete problems that require complex actions, you must use a web browser.
EdX recommends that you complete all of your graded assignments in a web browser on a computer.
In the edX mobile app, you can do problems that you answer in one of these ways.
You cannot take timed or proctored exams using the mobile app.
You can read and contribute to course discussions in the edX mobile apps whenever you have an Internet connection. In your course, select Discussion. You can then browse through different topics or search for words or phrases that interest you. For information about course discussions, see Participating in Course Discussions.
To download videos, you must be connected to the Internet. Select the “download” icon that appears to the right of a subsection or video name.
If you select download for a subsection, you download all of the videos in that subsection.
If you select download for a video, you download only that video.
This example lists subsections in a course and shows how many videos will download when you select the icon.
To download videos, you must be connected to the Internet. After you download a video, you can watch it at any time.
Course videos are optimized for mobile playback, but watching or downloading any video can result in heavy data use. EdX recommends using a Wi-Fi connection if you intend to watch or download a lot of videos. The edX mobile apps have a Download only on Wi-Fi setting that is enabled by default to help you avoid using your cellular network accidentally.
The number to the right of a subsection name indicates the number of videos in that subsection.
Rotate your phone until the video changes to landscape mode, or select “full screen” in the bottom right corner of the video player.
You can change video speeds on the iPhone app. While a video plays, select Settings (the “gear” icon) at the lower right, and then select Video Speed.
On the Android app, videos currently play only at their original speeds.
On the My Courses page, select the menu in the upper left corner.
Select My Settings.
Change the Wi-Fi only download setting.
By default, the apps are set so that they only download content, including videos, if you are on a Wi-Fi network. If you change this setting, you might exceed the data allowance for your cellular plan.
Each circle indicates whether you have already played a video. A blue circle means that you have not started playing the video. A half-filled circle means that you played part of the video. A gray circle means that you played the entire video.
If you have problems viewing videos, make sure that you have an Internet connection and then try to view or download the video again.
If problems persist, let us know. On the My Courses page, select the “menu” icon, and then select Submit Feedback.
