# DTMF Decoder vs Odmaster

The clearest difference is price: Odmaster at Free against DTMF Decoder's $0.99. Odmaster also leads on rating (3.8 vs 2.5) and update cadence (every 3 weeks vs every 19 months). DTMF Decoder's advantage is review sentiment (40% vs 29%) and iOS requirement (11.0 vs 14.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

Odmaster is free to download; DTMF Decoder costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Odmaster holds the better App Store score, 3.8 against 2.5. That said, the two scores are not equally well evidenced: Odmaster has 1.1K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 40% of DTMF Decoder's written reviews are positive against 29% of Odmaster's, so the app with the better star average is not the one people write more warmly about.

DTMF Decoder ships an update every 19 months, Odmaster every 3 weeks. The most recent releases landed on October 2, 2026 and October 3, 2026 respectively.
