ReceptionRating · Positive reviews · Number of ratings

Obstetrics Calculator holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: eMPendium has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of eMPendium's written reviews are positive against 55% of Obstetrics Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

eMPendium ships an update every 3 months, Obstetrics Calculator every 2 months. The most recent releases landed on June 5, 2026 and September 10, 2026 respectively.
