Microsoft is beta testing a new Launcher app for Android, an application that will completely take over your Android home screen and provide a new way to navigate through apps and contacts.
According to GSM Arena the app is called "Arrow" and offers three different homescreen options. The default features a row of your most recently used apps, with frequently used apps listed beneath. Under that, is the familiar menu button to open up a complete list of all of your apps.
To the left of the homescreen is a list of the people you have contacted most recently, and to the right is notes and reminders app. Swiping up also shows your most recent apps and contacts, presumably to make them easily accessible.
You can also set your phone wallpaper to change every day to match the Bing homepage image.
It isn't clear whether the launcher will come with any other Microsoft integration. We know Microsoft is working on Cortana for Android, so it would make sense to bundle that in too - but there is no sign of it yet.
The news comes just weeks after Microsoft essentially admitted defeat on its own Windows Phone platform. Whilst the company hasn't killed off Windows Phone entirely, it has massively cut staff and has made noises about only targeting specialist business users and the like, instead of normal consumers.
At the moment Arrow is only in private beta testing, but you can request an invite through the Arrow Google+ page.
