# Buteyko Pro vs Dual N

The clearest difference is rating: Buteyko Pro at 4.8 against Dual N's 4.1. Buteyko Pro also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 6 months). Dual N's advantage is iOS requirement (9.0 vs 15.0). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Dual N sells 1 one-off in-app purchase. Buteyko Pro asks for nothing beyond the download.

Buteyko Pro holds the better App Store score, 4.8 against 4.1. Both are backed by a comparable volume of ratings — 45 and 88 respectively. Written reviews complicate that: 50% of Buteyko Pro's written reviews are positive against 52% of Dual N's, so the app with the better star average is not the one people write more warmly about.

Buteyko Pro ships an update every 3 weeks, Dual N every 6 months. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
