# ACOG vs Motion

The clearest difference is rating: ACOG at 4.9 against Motion's 4.1. ACOG also leads on in-app purchases (none vs 4) and review sentiment (90% vs 60%). Motion's advantage is update cadence (monthly vs every 3 months) and iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. Motion sells 4 in-app purchases, starting at $1.99 per month. ACOG asks for nothing beyond the download.

ACOG holds the better App Store score, 4.9 against 4.1. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 31, 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 60% of Motion's.

ACOG ships an update every 3 months, Motion monthly. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
