Releasing a free app, get revenue from ads


I have a 2 questions regarding UE4 and free apps,

  1. Is it allowed to release UE4 developed products free? in stores like appstore and googleplay?

  2. Lets say my app is free and the only revenue i get from the in-app advertisement. The only royalties i have to pay to Epic is 5% of my ads revenue?

  1. Yes.
  2. Yes. You pay 5% from revenue that exceeds 3’000$ per quarter.

I recommend to read EULAfor the details

maybe a missing leading topic, I’m not releasing any app. I’m thinking develop a free mobile game as free and get revenues from ads

thanks you for clear answer

A game is an app.
