# SoundPrism vs Polywave

The clearest difference is rating: Polywave at 4.7 against SoundPrism's 4.2. SoundPrism's advantage is iOS requirement (9.0 vs 15.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. SoundPrism sells 10 one-off in-app purchases and Polywave sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Polywave holds the better App Store score, 4.7 against 4.2. Both are backed by a comparable volume of ratings — 74 and 34 respectively. Written reviews complicate that: 85% of SoundPrism's written reviews are positive against 80% of Polywave's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 7, 2026 and October 10, 2026 respectively.
