Verdict
The clearest difference is price: Musizi at Free against Theremin Touch's $2.99. Musizi also leads on review sentiment (80% vs 65%). Theremin Touch's advantage is rating (4.0 vs 1.0) and in-app purchases (none vs 1). On update cadence, ads, device support and iOS requirement there is nothing between them.

Musizi is free to download; Theremin Touch costs $2.99 up front. Musizi sells 1 one-off in-app purchase. Theremin Touch asks for nothing beyond the download.
Theremin Touch holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: Theremin Touch has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 65% of Theremin Touch's written reviews are positive against 80% of Musizi's, so the app with the better star average is not the one people write more warmly about.
Theremin Touch ships an update every 2 weeks, Musizi monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
