ReceptionRating · Positive reviews · Number of ratings

YDS Controller holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: YDS Controller has 176 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 44% of SWAM Alto Sax's written reviews are positive against 38% of YDS Controller's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SWAM Alto Sax ships an update every 2 months, YDS Controller every 4 months. Both last shipped on November 11, 2026.
