# ForSound vs CIRSS

The clearest difference is review sentiment: CIRSS at 100% against ForSound's 20%. ForSound's advantage is rating (2.7 vs 1.0) and ratings volume (26 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ForSound holds the better App Store score, 2.7 against 1.0. That said, the two scores are not equally well evidenced: ForSound has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 20% of ForSound's written reviews are positive against 100% of CIRSS's, so the app with the better star average is not the one people write more warmly about.

ForSound ships an update every 2 months, CIRSS every 4 months. The most recent releases landed on September 15, 2026 and June 25, 2026 respectively.
