# DTMF Dial vs Odmaster

The clearest difference is rating: Odmaster at 3.8 against DTMF Dial's 1.0. Odmaster also leads on update cadence (every 3 weeks vs every 27 months) and ratings volume (1.1K vs 5). DTMF Dial's advantage is iOS requirement (9.0 vs 14.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Odmaster holds the better App Store score, 3.8 against 1.0.

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.
