One Brain is inspired by the Stroop effect, a famous psychological test that measures how well you handle conflicting information. For example, it's harder to name the color of a word when the word itself spells a different color. This game challenges your whole brain as you fight to process the mixed signals and make the right call before time runs out. Game modes: • Colors: Does the word match the color it's written in? • Arrows: Is the arrow actually pointing the way it says it is? • Numbers: Is the math equation true or false? • Words: Which word matches the definition? How high can you score under pressure?

Verdict
One Brain and IQ Boost both sit at 4.4 stars, but that hides the real split: 59% of One Brain's written reviews are positive against 13% of IQ Boost's. One Brain also leads on update cadence (weekly vs every 5 weeks). IQ Boost's advantage is ratings volume (54K vs 297) and chart position (#79 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.

On the App Store both sit at effectively the same score — 4.4 for One Brain against 4.5 for IQ Boost. That said, the two scores are not equally well evidenced: IQ Boost has 54K ratings behind it against 297, so its average is the more settled of the two. Written reviews are what separate them: 59% of One Brain's written reviews are positive against 13% of IQ Boost's.
One Brain ships an update weekly, IQ Boost every 5 weeks. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
