# Q... vs Brain Dots

The clearest difference is rating: Brain Dots at 4.4 against Q...'s 2.7. Brain Dots also leads on ratings volume (8.2K vs 81) and update cadence (every 3 weeks vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Q... sells 4 one-off in-app purchases and Brain Dots sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Brain Dots holds the better App Store score, 4.4 against 2.7. That said, the two scores are not equally well evidenced: Brain Dots has 8.2K ratings behind it against 81, so its average is the more settled of the two. Written reviews complicate that: 51% of Q...'s written reviews are positive against 50% of Brain Dots's, so the app with the better star average is not the one people write more warmly about.

Q... ships an update every 3 months, Brain Dots every 3 weeks. The most recent releases landed on October 19, 2026 and October 20, 2026 respectively.
