ReceptionRating · Positive reviews · Number of ratings

Horucco holds the better App Store score, 4.1 against 3.0. 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: 74% of Horucco's written reviews are positive against 75% of Chromatic Harmonica PRO's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Horucco ships an update every 4 weeks, Chromatic Harmonica PRO every 10 days. The most recent releases landed on November 3, 2026 and November 2, 2026 respectively.
