# Decibel Shield vs Decibel

The clearest difference is update cadence: Decibel Shield at every 3 days against Decibel's monthly. Decibel Shield also leads on rating (4.7 vs 4.4). Decibel's advantage is iOS requirement (13.1 vs 15.6). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Decibel Shield sells 4 in-app purchases, starting at $1.99 per 7 days and Decibel sells 15 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Decibel Shield holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 608 and 250 respectively. Written reviews complicate that: 75% of Decibel Shield's written reviews are positive against 81% of Decibel's, so the app with the better star average is not the one people write more warmly about.

Decibel Shield ships an update every 3 days, Decibel monthly. The most recent releases landed on September 24, 2026 and September 9, 2026 respectively.
