The apps I have installed on my Prime are not visible in the Program catalog, and have the extension .hpappprgm, while programs have the extension .hpprgm. So for every app I install I can't see the source code. So how am I supposed to learn how to make an app? Sincerely, Karel.

The source code (and icon files, etc.) are included in the .zip files you downloaded from hpcalc.org. Extract those files and you can examine/study them and compare with the results running the Apps.
