ReceptionRating · Positive reviews · Number of ratings

pedsMRI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Thoracic Lymph Node Map has 25 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Thoracic Lymph Node Map's written reviews are positive against 67% of pedsMRI's, so the app with the better star average is not the one people write more warmly about.
