# IQ Test vs Brainchain

The clearest difference is rating: IQ Test at 4.4 against Brainchain's 4.0. IQ Test also leads on ratings volume (8K vs 1) and update cadence (every 6 weeks vs every 4 months). Brainchain's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. IQ Test sells 10 in-app purchases, starting at $3.99 per month and Brainchain sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

IQ Test holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: IQ Test has 8K ratings behind it against 1, so its average is the more settled of the two.

IQ Test ships an update every 6 weeks, Brainchain every 4 months. The most recent releases landed on November 8, 2026 and November 3, 2026 respectively.
