The Android launcher scene might be getting a little out of control -- even Nokia (whose X phones are now under Microsoft's wing) is getting into the game. The Finnish firm has just released Z Launcher, a home screen replacement that gets you to frequently-used apps, contacts and sites as quickly as possible. The software learns your habits and surfaces the content you're most likely to use based on where you are, what you're doing and the time of day. It might put your calendar app at the top when you're in the middle of the workday, or highlight Instagram when you're out on the town. You also don't have to dive into the app tray if you're looking for something specific; you can draw an item's first letter to bring up a narrow set of results.
