# Composia vs Horucco

The clearest difference is review sentiment: Horucco at 74% against Composia's 0%. Horucco also leads on ratings volume (20 vs 2). Composia's advantage is rating (4.5 vs 4.1) and iOS requirement (15.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Composia sells 1 one-off in-app purchase and Horucco sells 3 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Composia holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Horucco has 20 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of Composia's written reviews are positive against 74% of Horucco's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 weeks. The most recent releases landed on October 27, 2026 and November 3, 2026 respectively.
