Verdict
The clearest difference is price: Ham Radio Toolbox at Free against DTMF Decoder's $0.99. Ham Radio Toolbox also leads on rating (4.8 vs 2.5) and update cadence (every 6 days vs every 19 months). DTMF Decoder's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.1). On review sentiment, in-app purchases and device support there is nothing between them.
