Apps are ubiquitous. You can download thousands of apps to install whatever you want on your phone. An own extension was just a logical consequence.
Do you develop or program such apps? Do you sell apps? Or do you test them to give your professional opinion about them? Then a .app name is an ideal name for you.
Don't wait any longer and register your name under the .app extension.
