# ACOG vs ACR Guidance

The clearest difference is review sentiment: ACOG at 90% against ACR Guidance's 25%. ACOG also leads on rating (4.9 vs 3.1) and ratings volume (6.3K vs 12). ACR Guidance's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence, ads and in-app purchases 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 3.1. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 90% of ACOG's written reviews are positive against 25% of ACR Guidance's.

ACOG ships an update every 3 months, ACR Guidance every 2 months. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
