# Mood Detector vs Lie Detector Test

The clearest difference is in-app purchases: Lie Detector Test at none against Mood Detector's 1. Lie Detector Test also leads on ratings volume (270 vs 47) and review sentiment (28% vs 19%). Mood Detector's advantage is update cadence (every 3 months vs every 85 months) and rating (4.0 vs 3.6). On price, ads, monetization model 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, 4.0 against 3.6. That said, the two scores are not equally well evidenced: Lie Detector Test has 270 ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 19% of Mood Detector's written reviews are positive against 28% 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 85 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
