Surprisingly, I like this app. When I got my heart tempo up it detected I lied, when I slowed it down it worked. Really good for fake scenarios, but definitely didn't work when I lied (I'm a sociopath lol). Only bad thing would have to be the ads, there's one upon opening in popular form, one video form (5-15 seconds) and one or two for the next try.

This app is completely false. Neat gimmick though.
