It's Launcoogle, a(n) (useless) app written by me.
What can this do?
Install it, press home button, select Launcoogle, then you will know.
Why did you make this app?
I found that Google is better than any other launcher. You can launch apps, search contacts and do many things. I've used this for a while, and now I think I should take you out of the trap of normal launchers.
