Tired of hanging up your calls when you didn't want to? What about making a conference? Hold mode? silence mode?

Well this is the app you need!!

What it does?

When you answer a call, or make a call, a semi transparent screen will appear preventing you from doing things that you didn't want to, but if the person who you are talking with ends the call the screen will disappear. You can close the screen if you want.
