Verdict
The clearest difference is rating: 3D Model Viewer at 4.4 against Code Viewer's 3.4. 3D Model Viewer also leads on update cadence (weekly vs every 3 weeks) and ratings volume (350 vs 18). Code Viewer's advantage is review sentiment (49% vs 20%) and iOS requirement (7.0 vs 15.6). On price, ads, in-app purchases and monetization model 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. Code Viewer sells 1 one-off in-app purchase and 3D Model Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
3D Model Viewer holds the better App Store score, 4.4 against 3.4. That said, the two scores are not equally well evidenced: 3D Model Viewer has 350 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 49% of Code Viewer's written reviews are positive against 20% of 3D Model Viewer's, so the app with the better star average is not the one people write more warmly about.
Code Viewer ships an update every 3 weeks, 3D Model Viewer weekly. The most recent releases landed on October 7, 2026 and October 11, 2026 respectively.
