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. For steps on how to adjust the video quality of lectures you want to download on the mobile app, please click here.

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 Account > Download options > and toggle on the Download over 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.
