Falling Filter Challenge holds the better App Store score, 4.5 against 3.2. That said, the two scores are not equally well evidenced: Falling Filter Challenge has 1.1K ratings behind it against 114, so its average is the more settled of the two. Written reviews complicate that: 11% of Lie Detector's written reviews are positive against 10% of Falling Filter Challenge's, so the app with the better star average is not the one people write more warmly about.
Lie Detector ships an update every 8 days, Falling Filter Challenge every 4 months. The most recent releases landed on September 21, 2026 and September 24, 2026 respectively.
