Verdict

The call

The clearest difference is rating: ACOG at 4.9 against VisualDx's 4.4. ACOG also leads on in-app purchases (none vs 11) and ratings volume (6.3K vs 186). VisualDx's advantage is update cadence (fortnightly vs every 3 months) and chart position (#17 vs unranked). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ACOG holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: ACOG has 6.3K ratings behind it against 186, so its average is the more settled of the two. Written reviews point the same way: 84% of VisualDx's written reviews are positive against 90% of ACOG's.

UpkeepUpdate frequency

VisualDx ships an update fortnightly, ACOG every 3 months. The most recent releases landed on October 19, 2026 and October 18, 2026 respectively.
