Verdict
The clearest difference is ads: Intelligence Test at none against Lights's shown. Intelligence Test also leads on review sentiment (30% vs 0%) and iOS requirement (12.0 vs 15.0). Lights's advantage is update cadence (every 6 weeks vs every 5 months) and ratings volume (182 vs 18). On price, rating, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
Intelligence Test holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Lights has 182 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 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. Both last shipped on November 11, 2026.
