# Stem Split vs Spiral Chorus

The clearest difference is rating: Spiral Chorus at 5.0 against Stem Split's 2.3. Spiral Chorus also leads on monetization model (free vs free with in-app purchases) and ratings volume (15 vs 4). Stem Split's advantage is review sentiment (100% vs 89%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Stem Split sells 1 one-off in-app purchase and Spiral Chorus sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Spiral Chorus holds the better App Store score, 5.0 against 2.3. Both are backed by a comparable volume of ratings — 4 and 15 respectively. Written reviews complicate that: 100% of Stem Split's written reviews are positive against 89% of Spiral Chorus's, so the app with the better star average is not the one people write more warmly about.

Stem Split ships an update every 17 months, Spiral Chorus every 15 months. The most recent releases landed on September 15, 2026 and September 10, 2026 respectively.
