Verdict

The call

The clearest difference is price: Diagnosaurus® DDx at Free against STATworkUP® DDx Clinical Guide's $24.99. Diagnosaurus® DDx also leads on ratings volume (2.5K vs 12) and rating (4.8 vs 4.6). STATworkUP® DDx Clinical Guide's advantage is in-app purchases (none vs 1) and update cadence (fortnightly vs every 10 months). On ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Diagnosaurus® DDx holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Diagnosaurus® DDx has 2.5K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 69% of STATworkUP® DDx Clinical Guide's written reviews are positive against 53% of Diagnosaurus® DDx's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

STATworkUP® DDx Clinical Guide ships an update fortnightly, Diagnosaurus® DDx every 10 months. Both last shipped on November 1, 2026.
