Verdict
The clearest difference is rating: Dual N at 4.7 against Radiooooo's 4.0. Dual N also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (13.0 vs 15.0). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Radiooooo sells 2 in-app purchases, starting at $4.49 per month and Dual N sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Dual N holds the better App Store score, 4.7 against 4.0. Both are backed by a comparable volume of ratings — 774 and 1.2K respectively. Written reviews complicate that: 58% of Radiooooo's written reviews are positive against 55% of Dual N's, so the app with the better star average is not the one people write more warmly about.
Radiooooo ships an update every 2 months, Dual N every 3 weeks. Both last shipped on November 6, 2026.
