Looking for an app that changes your voice on the fly

[y0manda]

Anyone know of an app that changes your voice on the fly while talking on the phone? Its funny you see these movies that have been doing it 20+ years ago, but I can't find an app on the market. I see a few that changes your voice but only for recording and then playback.

BluffMyCall and CallFaker can both do it, but you have to pay for it. Check them out though!
