Decibel Meter Plus Pro is free to download; Plant Light Meter costs $2.99 up front. Decibel Meter Plus Pro sells 1 one-off in-app purchase. Plant Light Meter asks for nothing beyond the download.
Plant Light Meter holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Plant Light Meter has 1.1K ratings behind it against 81, so its average is the more settled of the two. Written reviews complicate that: 53% of Decibel Meter Plus Pro's written reviews are positive against 39% of Plant Light Meter's, so the app with the better star average is not the one people write more warmly about.
Decibel Meter Plus Pro ships an update every 2 months, Plant Light Meter fortnightly. Both last shipped on November 6, 2026.
