Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
