# IQ Test vs Brain Challenge

The clearest difference is ads: IQ Test at none against Brain Challenge's shown. IQ Test also leads on ratings volume (8K vs 40) and review sentiment (35% vs 22%). Brain Challenge's advantage is iOS requirement (12.0 vs 15.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. IQ Test sells 11 in-app purchases, starting at $3.99 per month and Brain Challenge 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 — 4.4 for IQ Test against 4.4 for Brain Challenge. That said, the two scores are not equally well evidenced: IQ Test has 8K ratings behind it against 40, so its average is the more settled of the two. Written reviews are what separate them: 35% of IQ Test's written reviews are positive against 22% of Brain Challenge's.

IQ Test ships an update every 6 weeks, Brain Challenge every 5 weeks. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
