SpoofApp  is a iPhone Caller ID Spoofing, Voice Changing, and Call Recording App.

It can change your voice to male or female, hide your true mobile number and records your calls.

If you don’t live in the US or Canada there’s no need to read this article, as the service is not available outside of the US or Canada.

I will try to explain this as good as possible but as I’m not living in a supported country i can’t really review this with all it’s features.
