# iRhino 3D vs BIMx

The clearest difference is rating: iRhino 3D at 4.6 against BIMx's 4.0. iRhino 3D also leads on monetization model (free vs free with in-app purchases) and update cadence (fortnightly vs every 6 weeks). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

iRhino 3D holds the better App Store score, 4.6 against 4.0. Both are backed by a comparable volume of ratings — 81 and 168 respectively. Written reviews complicate that: 55% of iRhino 3D's written reviews are positive against 60% of BIMx's, so the app with the better star average is not the one people write more warmly about.

iRhino 3D ships an update fortnightly, BIMx every 6 weeks. Both last shipped on October 24, 2026.
