Verdict

The call

The clearest difference is review sentiment: KETRA at 100% against Composer Express's 54%. KETRA also leads on update cadence (every 2 weeks vs every 4 months) and iOS requirement (7.0 vs 12.0). Composer Express's advantage is rating (4.7 vs 4.2) and ratings volume (31 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Composer Express holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Composer Express has 31 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 54% of Composer Express's written reviews are positive against 100% of KETRA's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Composer Express ships an update every 4 months, KETRA every 2 weeks. The most recent releases landed on September 12, 2026 and September 30, 2026 respectively.
