WHAT IS AN IQ TEST? An IQ test shows how you perform compared to other people. Intelligence itself is not clearly defined – it is simply what an IQ test measures. That's why only results of the same test can be compared: an IQ above 100 means you solved the tasks better than average, below 100 means worse. So don't take your score too seriously – see it as an exciting comparison with others!

Verdict
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.
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. 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.
