Lie Detector Test Truth Shock holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Lie Detector Test Truth Shock has 767 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 47% of Lie Detector Test Truth Shock's written reviews are positive against 100% of Optical Illusion Pro's, so the app with the better star average is not the one people write more warmly about.
