Seems like a scam – Genoa Travel Guide Offline Review

I got this because I wanted a map I could use with GPS offline, but when you click on the map, it prompts you to "unlock" it, which then requires an App Store password (a second time), so I suspect it's an in-app purchase, although it doesn't say "buy" or tell you if or how much you would be paying for the map. This should be clear, and it shouldn't say it includes a map, because it doesn't.
