Where do I find the program to go with the LEGO 51515?
The &quot;App&quot; page does seem to be hard to find at the moment. I found it by clicking on this little icon on the MINDSTORMS &quot;About&quot; page.

The app is distributed through various app stores:

Microsoft Store (Windows)
Apple App Store (macOS/iOS)
Google Play (Android/Cromebook)
Amazon App Store (Kindle Fire)

There isn't currently any option for Linux, but there is a 3rd party project call Pybricks that is working on supporting the 51515, so keep an eye on that if you use Linux.
