Verdict
The clearest difference is review sentiment: CodePin at 100% against 3D File Viewer's 33%. CodePin also leads on rating (5.0 vs 4.5) and update cadence (every 9 days vs every 3 weeks). 3D File Viewer's advantage is ratings volume (48 vs 1) and iOS requirement (16.6 vs 18.6). On price, ads, in-app purchases and monetization model there is nothing between them.

That said, the two scores are not equally well evidenced: 3D File Viewer has 48 ratings behind it against 1, so its average is the more settled of the two.

3D File Viewer ships an update every 3 weeks, CodePin every 9 days. The most recent releases landed on October 14, 2026 and October 1, 2026 respectively.
