# GranSample vs SonarRoom Audio Analysis Tool

The clearest difference is rating: GranSample at 4.6 against SonarRoom Audio Analysis Tool's 4.2. GranSample also leads on ratings volume (16 vs 5). SonarRoom Audio Analysis Tool's advantage is review sentiment (67% vs 40%) and monetization model (free vs free with in-app purchases).

Both are free to download. GranSample sells 1 one-off in-app purchase and SonarRoom Audio Analysis Tool sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

GranSample holds the better App Store score, 4.6 against 4.2. Both are backed by a comparable volume of ratings — 16 and 5 respectively. Written reviews complicate that: 40% of GranSample's written reviews are positive against 67% of SonarRoom Audio Analysis Tool's, so the app with the better star average is not the one people write more warmly about.
