ReceptionRating · Positive reviews · Number of ratings

Concentration Game, 9Bubbles holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Memory Match Brain Trainer has 1.3K ratings behind it against 45, so its average is the more settled of the two. Written reviews complicate that: 69% of Memory Match Brain Trainer's written reviews are positive against 55% of Concentration Game, 9Bubbles's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Memory Match Brain Trainer ships an update every 6 months, Concentration Game, 9Bubbles every 10 days. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
