Verdict
The clearest difference is review sentiment: Stem Split at 100% against Vocal Separator's 22%. Stem Split also leads on ads (none vs shown).

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Vocal Separator sells 1 one-off in-app purchase and Stem Split sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
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.
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.
