# Lie Detector vs QuestMe

The clearest difference is rating: QuestMe at 3.7 against Lie Detector's 2.7. QuestMe also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 8 months). Lie Detector's advantage is review sentiment (13% vs 0%) and ratings volume (30 vs 3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Lie Detector sells 4 one-off in-app purchases and QuestMe sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

QuestMe holds the better App Store score, 3.7 against 2.7. That said, the two scores are not equally well evidenced: Lie Detector has 30 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 13% of Lie Detector's written reviews are positive against 0% of QuestMe'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 months, QuestMe every 5 weeks. The most recent releases landed on October 27, 2026 and October 18, 2026 respectively.
