# ChordLab vs ScaleCoach Pro

The clearest difference is rating: ChordLab at 5.0 against ScaleCoach Pro's 2.0. ChordLab also leads on update cadence (every 3 months vs every 36 months) and iOS requirement (12.1 vs 15.6). ScaleCoach Pro's advantage is in-app purchases (none vs 10) and review sentiment (50% vs 21%). On price, ratings volume, ads and monetization model there is nothing between them.

ChordLab costs $3.99 and ScaleCoach Pro $3.99 up front. ChordLab sells 10 one-off in-app purchases. ScaleCoach Pro asks for nothing beyond the download.

ChordLab holds the better App Store score, 5.0 against 2.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 21% of ChordLab's written reviews are positive against 50% of ScaleCoach Pro's, so the app with the better star average is not the one people write more warmly about.

ChordLab ships an update every 3 months, ScaleCoach Pro every 36 months. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
