# ACOG vs The Bug Book

The clearest difference is in-app purchases: ACOG at none against The Bug Book's 1. ACOG also leads on ratings volume (6.3K vs 3) and update cadence (every 3 months vs every 15 months). The Bug Book's advantage is iOS requirement (11.0 vs 17.0). On price, rating, ads and monetization model there is nothing between them.

Both are free to download. The Bug Book sells 1 one-off in-app purchase. ACOG asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for ACOG against 5.0 for The Bug Book. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 3, so its average is the more settled of the two.

ACOG ships an update every 3 months, The Bug Book every 15 months. The most recent releases landed on September 23, 2026 and August 19, 2026 respectively.
