# Kulla vs Intelligence Test

The clearest difference is price: Intelligence Test at Free against Kulla's $1.99. Intelligence Test also leads on rating (4.6 vs 2.3) and ratings volume (18 vs 3). Kulla's advantage is review sentiment (72% vs 30%) and in-app purchases (none vs 1). On update cadence, ads, device support and iOS requirement there is nothing between them.

Intelligence Test is free to download; Kulla costs $1.99 up front. Intelligence Test sells 1 one-off in-app purchase. Kulla asks for nothing beyond the download.

Intelligence Test holds the better App Store score, 4.6 against 2.3. That said, the two scores are not equally well evidenced: Intelligence Test has 18 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 72% of Kulla's written reviews are positive against 30% of Intelligence Test's, so the app with the better star average is not the one people write more warmly about.

Kulla ships an update every 2 months, Intelligence Test every 5 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
