If you plan on being disconnected from the internet, you can save individual lectures, sections, or an entire course for offline viewing on the iOS mobile app. When you're in an offline environment, an orange phone icon will appear on courses that have lectures downloaded to your device.
Please note that practice activities like quizzes and practice tests, etc. cannot be downloaded and completed offline.
Save a Lecture for Offline Viewing
You can save lectures for offline viewing on your iOS device by following the steps below:
1. Tap on the grey download icon on the right hand side of the lecture title.
2. Once the lecture has finished downloading the download icon will turn color.
If you tap and hold on the download icon then the lecture options will appear. Select Save for Offline to download the lecture for offline viewing.
If you wish to remove the downloaded lecture, tap on the arrow icon and then select Remove Download.

Mobile Data Usage
To avoid unexpected data usage, we recommend downloading lectures to your device when it is connected to Wifi:
On iOS app, please go to More > Video options > and toggle on the Download via Wi-Fi only option
If you play downloaded lectures while your mobile data still is still turned on, the Udemy app will not use mobile data to load the video content. Some mobile data, however, may be used to load certain features in the background (About this course information, QA questions, etc) or initiate some server calls to update the course progress. As such, if you do not want to use any mobile data for the app, be sure to turn off the internet connection completely, or turn off mobile data usage for the Udemy app from the device’s system settings.
