# VisualDx vs FP Notebook

The clearest difference is rating: FP Notebook at 4.9 against VisualDx's 4.4. FP Notebook also leads on ratings volume (3.3K vs 186). VisualDx's advantage is review sentiment (84% vs 61%) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. VisualDx sells 11 in-app purchases, starting at $39.99 per month and FP Notebook sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

FP Notebook holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: FP Notebook has 3.3K 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 61% of FP Notebook's, so the app with the better star average is not the one people write more warmly about.

VisualDx ships an update fortnightly, FP Notebook every 2 months. Both last shipped on October 7, 2026.
