Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Theremin Touch ships an update every 2 weeks, Musizi monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
