Written reviews complicate that: 57% of dBMeter Pro's written reviews are positive against 66% of Decibel's, so the app with the better star average is not the one people write more warmly about.

dBMeter Pro ships an update every 5 months, Decibel every 2 months. The most recent releases landed on October 27, 2026 and October 31, 2026 respectively.
