If I recall correctly, if you bought an HP Prime calculator new-in-box, you would be able to download and use the HP Prime Pro app free of charge. Am I mistaken there or perhaps thinking of something else?
By the way, yes, the apps are now finally back on the Play Store again. lol
There is an app in the Windows App-Store HP Prime Free which is free for everyone, not just for those who bought the calculator. You can find it here:

There is as well an app HP Prime Pro in the Windows App-Store (
https://www.microsoft.com/de-de/p/hp-pri...verviewtab ) which costs about 20 Euros.
I am not sure what the difference is. According to the description of HP Prome Pro the programming language is included whereas the description of the HP Prime free this is not included. Perhaps that is the difference.
I use the HP Prime Pro on a rgular basis an I am very satisfied with it. And of course programming is inluded.
