# EFM Guide vs ACOG

The clearest difference is review sentiment: ACOG at 90% against EFM Guide's 50%. ACOG also leads on update cadence (every 3 months vs every 25 months) and rating (4.9 vs 4.5). EFM Guide's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model 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 4.5. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of EFM Guide's written reviews are positive against 90% of ACOG's.

EFM Guide ships an update every 25 months, ACOG every 3 months. The most recent releases landed on October 9, 2026 and October 15, 2026 respectively.
