# Odmaster vs WorldPenScan Go

The clearest difference is rating: WorldPenScan Go at 5.0 against Odmaster's 3.8. WorldPenScan Go also leads on device support (4 vs 2) and iOS requirement (12.1 vs 14.0). Odmaster's advantage is ratings volume (1.1K vs 2) and update cadence (every 3 weeks vs every 2 months). On price, review sentiment, 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.

WorldPenScan Go holds the better App Store score, 5.0 against 3.8. 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 25% of WorldPenScan Go'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, WorldPenScan Go every 2 months. The most recent releases landed on October 29, 2026 and October 9, 2026 respectively.
