ReceptionRating · Positive reviews · Number of ratings

SWAM Euphonium holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Koala Sampler has 1.5K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 88% of Koala Sampler's written reviews are positive against 50% of SWAM Euphonium's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Koala Sampler ships an update fortnightly, SWAM Euphonium every 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
