This smartphone app is called Crowdpilot.
It lets any user bring a third party into a conversation without alerting the person on the other end of the line, the modern day equivalent of picking up a landline while someone else is already on a call.
The app even allows the third party to talk to the app user without the other caller’s knowledge.
Upon launching Crowdpilot, users are given a choice of people to get in-call “advice” from, including Facebook friends and total strangers.
