Verdict
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.
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. 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 15, 2026 and October 17, 2026 respectively.
