# Lie Detector vs Falling Filter

The clearest difference is rating: Falling Filter at 4.6 against Lie Detector's 3.2. Falling Filter also leads on ads (none vs shown) and ratings volume (2.3K vs 150). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Lie Detector sells 1 one-off in-app purchase and Falling Filter sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Falling Filter holds the better App Store score, 4.6 against 3.2. That said, the two scores are not equally well evidenced: Falling Filter has 2.3K ratings behind it against 150, so its average is the more settled of the two.
