# Intelligence Test vs Lights

The clearest difference is ads: Intelligence Test at none against Lights's shown. Intelligence Test also leads on review sentiment (30% vs 0%). Lights's advantage is update cadence (every 6 weeks vs every 5 months) and ratings volume (130 vs 16). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Intelligence Test sells 1 one-off in-app purchase and Lights sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Intelligence Test against 4.4 for Lights. That said, the two scores are not equally well evidenced: Lights has 130 ratings behind it against 16, so its average is the more settled of the two. Written reviews are what separate them: 30% of Intelligence Test's written reviews are positive against 0% of Lights's.

Intelligence Test ships an update every 5 months, Lights every 6 weeks. The most recent releases landed on September 13, 2026 and September 8, 2026 respectively.
