A long time ago in Android land, a new launcher appeared in the Play Store. Called Aviate, it promised features that were, at that point in time, unique and relatively unheard of. The gist was that the launcher would predict what apps you would need, based on the time of day and later your location and other factors. It was supposed to make life easier by doing the homescreen customization for you, but my experience with it proved that it was merely a disappointment and a frustration.
