I got the free version… It did show ads… At first… but then I pulled down notifications, a scroll bar appeared on the side, and the ads disappeared permanently with it only saying "Buy full version to remove ads," and it didn't show ads again until I pulled down notifications again (in about half an hour).
I don't know, I never used ads before that bar "buy full..." is supposed to be there permanently, even if there are no ads, but I have no idea why they didn't load after you pulled down notification thingy. They are not related to eachother, the app can't even know about it so there is nothing I can do to fix it. It may be bug on apple's side or maybe it was just coincidence? (I doubt that)
Pretty awesome eye candy (from what I saw on the YouTube video).
A few remarks, however:
1) For the first half of the video, why was the quality set to "Low"? were you using an old iPhone device in this demonstration?
2) In the second half of the video, when the device is turned horizontally and the screen is split in half, the menu screen doesn't turn accordingly and stays in the vertical position. Perhaps this could be fixed with an updated version?
