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
The clearest difference is review sentiment: Brain Games at 84% against One Brain's 59%. Brain Games also leads on ratings volume (25K vs 297) and rating (4.7 vs 4.4). On price, update cadence, ads and in-app purchases 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 Games sells 11 in-app purchases, starting at $3.99 per 7 days and One Brain sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Brain Games holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Brain Games has 25K ratings behind it against 297, so its average is the more settled of the two. Written reviews point the same way: 84% of Brain Games's written reviews are positive against 59% of One Brain's.
Brain Games ships an update fortnightly, One Brain weekly. Both last shipped on September 24, 2026.
