# Mood Detector vs Lie Detector Test

The clearest difference is rating: Mood Detector at 3.9 against Lie Detector Test's 3.4. Mood Detector also leads on update cadence (every 3 months vs every 42 months). Lie Detector Test's advantage is in-app purchases (none vs 1) and ratings volume (1.6K vs 45). On price, ads and device support there is nothing between them.

Both are free to download. Mood Detector sells 1 one-off in-app purchase. Lie Detector Test asks for nothing beyond the download.

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.

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.
