# Brain Challenge vs IQ Test

The clearest difference is ads: IQ Test at none against Brain Challenge's shown. IQ Test also leads on ratings volume (8K vs 66). Brain Challenge's advantage is review sentiment (61% vs 34%) and update cadence (every 10 days vs every 6 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Brain Challenge sells 2 one-off in-app purchases and IQ Test sells 10 in-app purchases, starting at $3.99 per month. 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 Brain Challenge against 4.4 for IQ Test. That said, the two scores are not equally well evidenced: IQ Test has 8K ratings behind it against 66, so its average is the more settled of the two. Written reviews are what separate them: 61% of Brain Challenge's written reviews are positive against 34% of IQ Test's.

Brain Challenge ships an update every 10 days, IQ Test every 6 weeks. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
