ReceptionRating · Positive reviews · Number of ratings

Math Bridges holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Math Bridges has 2.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Add Sub K's written reviews are positive against 66% of Math Bridges's, so the app with the better star average is not the one people write more warmly about.
