# VisualDx vs Mohs Appropriate Use Criteria

The clearest difference is rating: Mohs Appropriate Use Criteria at 5.0 against VisualDx's 4.4. Mohs Appropriate Use Criteria also leads on in-app purchases (none vs 10). VisualDx's advantage is update cadence (fortnightly vs every 8 months) and ratings volume (186 vs 6). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. VisualDx sells 10 in-app purchases, starting at $39.99 per month. Mohs Appropriate Use Criteria asks for nothing beyond the download.

Mohs Appropriate Use Criteria holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: VisualDx has 186 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 84% of VisualDx's written reviews are positive against 75% of Mohs Appropriate Use Criteria's, so the app with the better star average is not the one people write more warmly about.

VisualDx ships an update fortnightly, Mohs Appropriate Use Criteria every 8 months. Both last shipped on November 1, 2026.
