# Odmaster vs Firstnum

The clearest difference is review sentiment: Firstnum at 100% against Odmaster's 29%. Odmaster's advantage is rating (3.8 vs 3.0) and ratings volume (1.1K vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

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 3.0. That said, the two scores are not equally well evidenced: Odmaster has 1.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of Odmaster's written reviews are positive against 100% of Firstnum's, so the app with the better star average is not the one people write more warmly about.

Odmaster ships an update every 3 weeks, Firstnum every 5 weeks. The most recent releases landed on September 27, 2026 and September 3, 2026 respectively.
