# iRhino 3D vs CDR

The clearest difference is in-app purchases: iRhino 3D at none against CDR's 1. iRhino 3D also leads on ratings volume (83 vs 1) and update cadence (every 3 weeks vs every 2 months). CDR's advantage is rating (5.0 vs 4.6) and iOS requirement (11.0 vs 17.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. CDR sells 1 in-app purchase, starting at $14.99 per year. iRhino 3D asks for nothing beyond the download.

CDR holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: iRhino 3D has 83 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 55% of iRhino 3D's written reviews are positive against 50% of CDR's, so the app with the better star average is not the one people write more warmly about.

iRhino 3D ships an update every 3 weeks, CDR every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
