Apparently Agile Messenger is not the only app by Agile developers on the App Store. Here, comes Agile Lie Detector. Not a very professional tool, but a good utility that shows you result in real time i.e. as the person speaks. The app analyses speech / voice and no other gestures, so this means that even a voice recording can be played via a speaker and tested by this app.
If at all, I would use this as a fun app and nothing serious.
