Verdict
The clearest difference is price: iRhino 3D at Free against ZIG SIM PRO's $3.99. iRhino 3D also leads on rating (4.6 vs 3.9) and ratings volume (80 vs 8). ZIG SIM PRO's advantage is chart position (#189 vs unranked) and iOS requirement (13.0 vs 17.0). On review sentiment, ads, in-app purchases and device support there is nothing between them.

iRhino 3D is free to download; ZIG SIM PRO costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
iRhino 3D holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: iRhino 3D has 80 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 55% of iRhino 3D's written reviews are positive against 60% of ZIG SIM PRO's, so the app with the better star average is not the one people write more warmly about.
iRhino 3D ships an update fortnightly, ZIG SIM PRO monthly. The most recent releases landed on September 30, 2026 and September 22, 2026 respectively.
