Verdict
The clearest difference is rating: Radio ID at 3.6 against DTMF Decoder's 2.5. Radio ID also leads on review sentiment (64% vs 40%) and update cadence (every 7 months vs every 19 months). DTMF Decoder's advantage is iOS requirement (11.0 vs 16.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
