ReceptionRating · Positive reviews · Number of ratings

Unblock holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Brain Challenge has 25 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Brain Challenge's written reviews are positive against 0% of Unblock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Brain Challenge ships an update every 2 months, Unblock every 61 months. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
