Verdict
The clearest difference is rating: iRhino 3D at 4.6 against Arkio's 3.1. iRhino 3D also leads on in-app purchases (none vs 5) and ratings volume (84 vs 7). Arkio's advantage is review sentiment (80% vs 55%) and device support (4 vs 2). On price, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Arkio sells 5 in-app purchases, starting at $19.99 per month. iRhino 3D asks for nothing beyond the download.
iRhino 3D holds the better App Store score, 4.6 against 3.1. That said, the two scores are not equally well evidenced: iRhino 3D has 84 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 55% of iRhino 3D's written reviews are positive against 80% of Arkio'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, Arkio monthly. The most recent releases landed on November 10, 2026 and November 2, 2026 respectively.
