Verdict

The call

The clearest difference is review sentiment: Stem Split at 100% against Vocal Separator's 22%. Stem Split also leads on ads (none vs shown). Vocal Separator's advantage is update cadence (every 3 days vs every 17 months) and rating (2.7 vs 2.3). On price, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Vocal Separator holds the better App Store score, 2.7 against 2.3. That said, the two scores are not equally well evidenced: Vocal Separator has 39 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 22% of Vocal Separator's written reviews are positive against 100% of Stem Split's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Vocal Separator ships an update every 3 days, Stem Split every 17 months. The most recent releases landed on September 6, 2026 and September 15, 2026 respectively.
