ReceptionRating · Positive reviews · Number of ratings

Karel the Robot holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Score has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Karel the Robot's written reviews are positive against 73% of Score's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Karel the Robot ships an update every 20 months, Score every 3 months. The most recent releases landed on October 6, 2026 and October 31, 2026 respectively.
