# Decibel Meter vs HYLA

The clearest difference is rating: HYLA at 5.0 against Decibel Meter's 4.3. HYLA also leads on in-app purchases (none vs 2) and ads (none vs shown). Decibel Meter's advantage is ratings volume (222 vs 2) and review sentiment (40% vs 18%). On price, update cadence and device support there is nothing between them.

Both are free to download. Decibel Meter sells 2 in-app purchases, starting at $0.99 per month. HYLA asks for nothing beyond the download.

HYLA holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Decibel Meter has 222 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 40% of Decibel Meter's written reviews are positive against 18% of HYLA's, so the app with the better star average is not the one people write more warmly about.

Decibel Meter ships an update every 3 weeks, HYLA every 6 weeks. The most recent releases landed on September 17, 2026 and June 1, 2026 respectively.
