As a side effect, concentration, memory, and processing speed are also improved. This app is free and offers 4 different exercises, which can help you achieve great results on their own. In addition, we recommend paid apps that offer an even bigger range of activities for your own personal development. Try it out for yourself. Fun is guaranteed!

Verdict
The clearest difference is in-app purchases: BRAIN at none against IQ Test's 11. BRAIN also leads on rating (4.7 vs 4.4) and review sentiment (50% vs 35%). IQ Test's advantage is update cadence (every 6 weeks vs every 27 months) and ratings volume (8K vs 3). On price, ads and device support 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. IQ Test sells 10 in-app purchases, starting at $3.99 per month. BRAIN asks for nothing beyond the download.
BRAIN holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: IQ Test has 8K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of BRAIN's written reviews are positive against 35% of IQ Test's.
BRAIN ships an update every 27 months, IQ Test every 6 weeks. The most recent releases landed on October 13, 2026 and October 18, 2026 respectively.
