Verdict
The clearest difference is price: Odmaster at Free against DTMFdec's $2.99. Odmaster also leads on update cadence (every 3 weeks vs every 25 months) and rating (3.8 vs 3.4). DTMFdec's advantage is iOS requirement (12.4 vs 14.0). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Odmaster is free to download; DTMFdec costs $2.99 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 3.4. That said, the two scores are not equally well evidenced: Odmaster has 1.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 33% of DTMFdec'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.
DTMFdec ships an update every 25 months, Odmaster every 3 weeks. The most recent releases landed on October 11, 2026 and October 13, 2026 respectively.
