# ACOG vs iPrenatal

The clearest difference is ratings volume: ACOG at 6.3K against iPrenatal's 26. iPrenatal's advantage is review sentiment (100% vs 90%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.9 for ACOG against 5.0 for iPrenatal. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 26, so its average is the more settled of the two. Written reviews are what separate them: 90% of ACOG's written reviews are positive against 100% of iPrenatal's.

ACOG ships an update every 3 months, iPrenatal every 4 months. The most recent releases landed on September 30, 2026 and September 17, 2026 respectively.
