Mobile and Tablet Support Details

All CS Discoveries, CS Principles, and Intro to App Lab courses are not compatible with tablets or mobile devices - a full keyboard and mouse (or touchpad, like on MacBooks) are required. Most tablets are not supported, with the following exceptions:

  • Microsoft Surface Pro with an external keyboard
  • iPad running iPadOS 13.4 or later with an external keyboard and an external mouse or touchpad

All other content, such as K-5 courses (Computer Science Fundamentals) and Hour of Code activities are compatible on iPads and Chromebooks in addition to all other modern tablets and laptop or desktop computers.

Mobile Phones

Our Hour of Code activities and CS Fundamentals courses can be completed on mobile phones. While these activities are usable, they are not optimized for a mobile phone experience and have some known limitations (e.g. touch targets may be small, accessory elements may display offscreen, and text may be difficult to input using the on-screen keyboard). The CS Discoveries, CS Principles, and Intro to App Lab courses are not usable on mobile phones.

 

Videos

We use YouTube to embed videos into Code.org and our online learning platform. For schools with YouTube blocked, we attempt to display a Code.org hosted video player instead.

You can test your browser's settings to see if YouTube is blocked and to verify that fallback video player will work for your classroom at code.org/educate/IT

 

Special settings for Google Apps/G-Suite users

If you're a G-suite administrator, be sure to check what your restriction settings are for YouTube. If you have specified the "Strict Restricted YouTube Access" setting or if you see messages stating 'this video has been restricted', you can add our channel to the approved list of channels. See this guide from Google to learn about how to add our channel to the approved list. You can also see this guide to learn more about different settings and which is best for your classroom.

If you are experiencing issues with videos in your classroom, contact us here.
