ReceptionRating · Positive reviews · Number of ratings

3D Heart Anatomy holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: EchoCalc has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 49% of EchoCalc's written reviews are positive against 0% of 3D Heart Anatomy's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EchoCalc ships an update monthly, 3D Heart Anatomy every 4 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
