From Mr. Number:
Let your friends know when you're free for a call and when you're busy. Block calls from people you don't want to hear from again. Find out who is calling when you don't recognize the number (US only). Look up every new number that you dial so you can add them to contacts with one tap (US only). Free: Status for Calling and TextingLet friends know when you're free for a call, when you prefer text, and when you're tied up. Send all your calls to voicemail and let your friends know when you're free again. You can even text your status to anyone who calls when you are busy.
