This is a pretty cool app, but as I've gotten a little older I have learned to tell when people are lying or not. Now there are those experts who can lie with a straight face and have perfected the art of deception but yeah this is still a cool concept. I also have learned that knowing whether or not someone is lying sometimes isn't always the best thing to know. I guess that is why they say truth hurts. I am pretty interested though please keep us posted on this app
