ReceptionRating · Positive reviews · Number of ratings

apeMatrix holds the better App Store score, 4.7 against 2.3. That said, the two scores are not equally well evidenced: apeMatrix has 84 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 78% of Piano Chords Compass's written reviews are positive against 73% of apeMatrix's, so the app with the better star average is not the one people write more warmly about.
