Verdict
The clearest difference is rating: RepeaterPhone at 4.4 against DTMF Decoder's 2.5. RepeaterPhone also leads on review sentiment (71% vs 40%) and update cadence (every 2 months vs every 19 months). DTMF Decoder's advantage is price ($0.99 vs $7.99) and iOS requirement (11.0 vs 15.0). On ads, in-app purchases and monetization model there is nothing between them.
