# Sound Meter HQ vs Renault Radio Code

The clearest difference is review sentiment: Renault Radio Code at 84% against Sound Meter HQ's 38%. Renault Radio Code also leads on monetization model (free vs free with in-app purchases). Sound Meter HQ's advantage is rating (4.8 vs 3.0) and ratings volume (349 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sound Meter HQ sells 1 one-off in-app purchase and Renault Radio Code sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sound Meter HQ holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Sound Meter HQ has 349 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 38% of Sound Meter HQ's written reviews are positive against 84% of Renault Radio Code's, so the app with the better star average is not the one people write more warmly about.

Sound Meter HQ ships an update every 4 months, Renault Radio Code every 2 months. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
