Verdict
The clearest difference is rating: Obstetrics Calculator at 5.0 against eMPendium's 3.4. eMPendium's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Obstetrics Calculator sells 2 in-app purchases, starting at $1.99 per month. eMPendium asks for nothing beyond the download.
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.
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.
