# Instruments Free vs Sound Museum

The clearest difference is rating: Sound Museum at 3.5 against Instruments Free's 2.1. Sound Museum also leads on update cadence (every 4 months vs every 19 months) and iOS requirement (9.0 vs 17.6). Instruments Free's advantage is review sentiment (51% vs 25%) and ratings volume (54 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Sound Museum holds the better App Store score, 3.5 against 2.1. That said, the two scores are not equally well evidenced: Instruments Free has 54 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 51% of Instruments Free's written reviews are positive against 25% of Sound Museum's, so the app with the better star average is not the one people write more warmly about.

Instruments Free ships an update every 19 months, Sound Museum every 4 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
