Someone suggested a pay-for app in another question and when I looked it up, it seemed it didn't have any trial version that has the feature for which I'd pay.
Now, I will not pay for something I have never seen working, even if it's only 4€ and so I was wondering whether I missed something or whether it's usual for pay-for apps to charge before you even can try it?
(This app, Moon+ Reader, does have a free version, but I'm specifically interested in a feature of the pay-for version, so the limited free version doesn't help.)
It seems like a very long time (maybe never) that I payed for any software on my desktop where there wasn't a demo of some sort to try out the key features you payed for.
