ReceptionRating · Positive reviews · Number of ratings

Mood Detector holds the better App Store score, 3.9 against 3.4. That said, the two scores are not equally well evidenced: Lie Detector Test has 1.6K ratings behind it against 45, so its average is the more settled of the two. Written reviews complicate that: 19% of Mood Detector's written reviews are positive against 36% of Lie Detector Test's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mood Detector ships an update every 3 months, Lie Detector Test every 42 months. The most recent releases landed on October 6, 2026 and October 10, 2026 respectively.
