# DoCube vs 3D Model Viewer & Converter

The clearest difference is review sentiment: DoCube at 100% against 3D Model Viewer & Converter's 43%. DoCube also leads on rating (4.6 vs 1.5) and ratings volume (11 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. DoCube sells 1 one-off in-app purchase and 3D Model Viewer & Converter sells 14 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

DoCube holds the better App Store score, 4.6 against 1.5.
