Verdict
The clearest difference is review sentiment: Practical Gastroenterology at 100% against Diagnosaurus® DDx's 53%. Practical Gastroenterology also leads on in-app purchases (none vs 1) and iOS requirement (10.2 vs 15.0). Diagnosaurus® DDx's advantage is rating (4.8 vs 4.0) and ratings volume (2.5K vs 1). On price, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Diagnosaurus® DDx sells 1 one-off in-app purchase. Practical Gastroenterology asks for nothing beyond the download.
Diagnosaurus® DDx holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Diagnosaurus® DDx has 2.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Practical Gastroenterology'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.
Practical Gastroenterology ships an update every 14 months, Diagnosaurus® DDx every 10 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
