It makes sense that the words are embarrassingly generic, they’re descriptor terms that every dev uses to goose their app downloads. An HD version of an app is a well-accepted notion that it’s better. An app that says it’s free? Of course that’s going to get a lot of love. What’s hilarious though is Android’s list where words like Wallpaper and Theme dominate the list — people love to customise and blingee their phones!

HD was predictable for iOS
The benefit of everyone having the same screens I suppose. You see exactly what the developers intended,
Not everyone has the same screens. The iPhone and iPad have different screens, therefore sticking an HD in there somewhere to differentiate resolution quality on each device and their various iterations (even though all of the iScreens may still be classified HD) makes sense.
Wallpaper apps are easy to make for Android and are basically the scummy spam apps of the platform.
