iOS Copyright/Image use question

[DipDiveDodge]

I've got a quick question about image use in applications. The game "LogosQuiz" uses hundreds of corporate logos. The app is free, but there are in-app purchases available. I was wondering if the developer has to pay royalties to the companies who own the logos?

Since they are public logo's, and he's not actually earning money by selling the logo's, that shouldn't be a problem as far as i know.

We can probably speculate but a copyright/trademark lawyer would be better equipped to answer this question, especially in regards to fair-use and making money off them.
