Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Odmaster holds the better App Store score, 3.8 against 1.0. 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: 36% of DTMF Dial'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 Dial ships an update every 27 months, Odmaster every 3 weeks. The most recent releases landed on November 1, 2026 and November 13, 2026 respectively.
