Is this app only available in the US app store or something? I tried on my iOS device here in Australia, and a whole heap of other mapping apps are appearing in search results instead, when the query string is "magic earth". iOS App Store is even autocompleting to "magic earth navigation & apps" but no Magic Earth app appears in the results.
