"Have you ever," asks app developers Magic Tap, "been in the situation where you need the perfect excuse
to get out of the room or step out of an annoying conversation? Easy:
Open FakeCalls and within seconds or minutes the application will
simulate a fake call. (No real calls are made; this is just simulation.
Good news is: you are the only one who knows that!). Then answer the
call, decline it or just let the phone ring to fake a missed call."
The following YouTube video demonstrates further:
And if you should feel guilty about using your poor innocent iPhone to scam your way out of face time with real people, take comfort in the fact that (a) the app only costs US$0.99 and (b) Magic Tap will donate 10% of their earnings to the Mi Sangre Foundation charity.
