# Audio One vs Stem Split

The clearest difference is review sentiment: Stem Split at 100% against Audio One's 25%. Audio One's advantage is rating (4.5 vs 2.3) and update cadence (every 2 months vs every 17 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Audio One sells 5 in-app purchases, starting at $2.99 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.

Audio One holds the better App Store score, 4.5 against 2.3. That said, the two scores are not equally well evidenced: Audio One has 197 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 25% of Audio One'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.

Audio One ships an update every 2 months, Stem Split every 17 months. The most recent releases landed on September 23, 2026 and September 15, 2026 respectively.
