# iRhino 3D vs 3D Model Viewer

The clearest difference is in-app purchases: iRhino 3D at none against 3D Model Viewer's 5. iRhino 3D also leads on ads (none vs shown) and rating (4.6 vs 4.2). 3D Model Viewer's advantage is ratings volume (327 vs 82) and iOS requirement (15.6 vs 17.0). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. 3D Model Viewer sells 5 one-off in-app purchases. iRhino 3D asks for nothing beyond the download.

iRhino 3D holds the better App Store score, 4.6 against 4.2. Both are backed by a comparable volume of ratings — 82 and 327 respectively. Written reviews complicate that: 55% of iRhino 3D's written reviews are positive against 59% of 3D Model Viewer's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 1, 2026.
