# BComposer Scales vs Functional Harmony

The clearest difference is rating: Functional Harmony at 4.9 against BComposer Scales's 3.0. Functional Harmony also leads on in-app purchases (none vs 1) and ratings volume (24 vs 1). BComposer Scales's advantage is review sentiment (100% vs 83%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. BComposer Scales sells 1 one-off in-app purchase. Functional Harmony asks for nothing beyond the download.

Functional Harmony holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Functional Harmony has 24 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of BComposer Scales's written reviews are positive against 83% of Functional Harmony's, so the app with the better star average is not the one people write more warmly about.

BComposer Scales ships an update every 12 months, Functional Harmony every 6 months. The most recent releases landed on October 5, 2026 and October 12, 2026 respectively.
