# Brain X vs NBack

The clearest difference is rating: NBack at 5.0 against Brain X's 4.6. NBack also leads on review sentiment (100% vs 71%). Brain X's advantage is update cadence (every 3 days vs every 2 months) and ratings volume (66 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Brain X sells 7 in-app purchases, starting at $6.99 per 7 days and NBack sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

NBack holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Brain X has 66 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 71% of Brain X's written reviews are positive against 100% of NBack's.

Brain X ships an update every 3 days, NBack every 2 months. The most recent releases landed on October 24, 2026 and October 11, 2026 respectively.
