Verdict

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Decibel Meter Plus Pro ships an update every 2 months, Plant Light Meter fortnightly. Both last shipped on November 6, 2026.
