Fun fact KGWZ released one of their albums completly free (i guess public domain) and encourage you to play with it as much as you want :)

no, it might be because there aren’t any reviews in my language. But they could still show the star count, weird

It doesn’t have any rating (or maybe it just doesn’t show them to me) and you said that it has a rating of 3.6. There is another app called the same that has rating of 3.7

I don’t think you found the vorrect one. I guess the one they are reffering to is made by Markus Fisch. It is also available on Fdroid
