# Mood Detector vs Lie Detector Test

Mood Detector and Lie Detector Test both sit at 4.0 stars, but that hides the real split: 57% of Lie Detector Test's written reviews are positive against 19% of Mood Detector's. Lie Detector Test also leads on iOS requirement (9.0 vs 14.0). Mood Detector's advantage is ratings volume (47 vs 14). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Mood Detector sells 1 one-off in-app purchase and Lie Detector Test sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Mood Detector holds the better App Store score, 4.0 against 3.8. Both are backed by a comparable volume of ratings — 47 and 14 respectively. Written reviews complicate that: 19% of Mood Detector's written reviews are positive against 57% of Lie Detector Test's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
