If you’ve ever searched for a wallpaper in the Google Play Store, chances are you were met by a never ending list of results. That’s because the word “Wallpaper” just happens to be the number one most frequent word in an Android app title. In fact, 26,900 Android app titles contain the word “Wallpaper” according to a list compiled by app discovery site App Brain. App Brain decided to create the list after a similar one consisting of the top most frequent words used in iOS app titles was released by Appsfire.
