# Brain Games vs One Brain

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.

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. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
