Thank you for replying so promptly, and excuse me for responding in kind. It was very kind of you to provide raw data on sales even tough you didn't need to disclose it. It really helps an outsider to grasp what to expect from similar scenarios.
I always tought that optional donations on itch where not a real revenue strategy, but merely a tip, a bonus, for something that the developers would already give for free even if donations where not available, and the donations you got in april where in fact more than I would expect (even though I don't have any other dataset to compare to).
But the difference from steam to itch, not only in value, but mainly in sale units, really staggers me. I would expect that a non-free product on itch would maybe sell a bit more units than pixelorama did in april, but I would also expect the sale units to still be really below what you got on steam.
I do intend to put a non-game app on steam but unfortunately it is not related to content creation and according to steam they currently are not accepting non-game apps that are not related to content creation

Maybe I could gameify the app to work around the restriction, but I would risk having the submission being denied.
Anyways, thanks again for the reply, you really did help me =)
Edit: the reddit link is old, but when I paid the steam direct product submission fee last week and had to select if I was submiting an app or game, I have seen that exact same message. To be exact, a short sentence about publishing non-game software and a link that led me to somewhere in the docs where I could see that exact same text they put in the reddit link.
