ReceptionRating · Positive reviews · Number of ratings

Music Separator AI holds the better App Store score, 4.3 against 2.3. That said, the two scores are not equally well evidenced: Music Separator AI has 44 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Stem Split's written reviews are positive against 0% of Music Separator AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Stem Split ships an update every 17 months, Music Separator AI every 2 months. The most recent releases landed on October 2, 2026 and October 11, 2026 respectively.
