# VisualDx vs UpToDate Expert AI

The clearest difference is review sentiment: VisualDx at 84% against UpToDate Expert AI's 43%. VisualDx also leads on chart position (#13 vs #105) and iOS requirement (16.4 vs 26.0). UpToDate Expert AI's advantage is rating (4.8 vs 4.4) and ratings volume (2.8K vs 186). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. VisualDx sells 10 in-app purchases, starting at $39.99 per month and UpToDate Expert AI sells 1 in-app purchase, starting at $89.00 per month. Whichever you choose, the download price is not the number that matters.

UpToDate Expert AI holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: UpToDate Expert AI has 2.8K ratings behind it against 186, so its average is the more settled of the two. Written reviews complicate that: 84% of VisualDx's written reviews are positive against 43% of UpToDate Expert AI's, so the app with the better star average is not the one people write more warmly about.

VisualDx ships an update fortnightly, UpToDate Expert AI every 2 weeks. Both last shipped on November 13, 2026.
