# One Brain vs IQ Boost

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.

Both are free to download. One Brain sells 1 one-off in-app purchase and IQ Boost sells 10 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

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.
