# 3D Model Viewer vs SolidInsight

The clearest difference is review sentiment: SolidInsight at 100% against 3D Model Viewer's 59%. SolidInsight also leads on ads (none vs shown) and rating (4.4 vs 4.2). 3D Model Viewer's advantage is ratings volume (327 vs 7). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 3D Model Viewer sells 5 one-off in-app purchases and SolidInsight sells 3 in-app purchases, starting at $46.99 per year. Whichever you choose, the download price is not the number that matters.

SolidInsight holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: 3D Model Viewer has 327 ratings behind it against 7, so its average is the more settled of the two.
