# ACOG vs Simple Pregnancy Wheel

The clearest difference is ratings volume: ACOG at 6.3K against Simple Pregnancy Wheel's 126. Simple Pregnancy Wheel's advantage is review sentiment (100% vs 90%) and iOS requirement (12.1 vs 17.0). 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.

ACOG holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 126, so its average is the more settled of the two. Written reviews complicate that: 90% of ACOG's written reviews are positive against 100% of Simple Pregnancy Wheel's, so the app with the better star average is not the one people write more warmly about.

ACOG ships an update every 3 months, Simple Pregnancy Wheel every 6 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
