# AI Vocal Remover vs Stem Split

The clearest difference is rating: AI Vocal Remover at 4.6 against Stem Split's 2.6. AI Vocal Remover also leads on update cadence (every 3 weeks vs every 17 months) and ratings volume (627 vs 5). Stem Split's advantage is ads (none vs shown) and review sentiment (100% vs 77%). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. AI Vocal Remover sells 6 in-app purchases, starting at $1.49 per 7 days and Stem Split sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AI Vocal Remover holds the better App Store score, 4.6 against 2.6. That said, the two scores are not equally well evidenced: AI Vocal Remover has 627 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 77% of AI Vocal Remover'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.

AI Vocal Remover ships an update every 3 weeks, Stem Split every 17 months. Both last shipped on October 24, 2026.
