ReceptionRating · Positive reviews · Number of ratings

Postage Stamp Camera holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: Decibel Meter Plus Pro has 81 ratings behind it against 15, 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 50% of Postage Stamp Camera's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on November 6, 2026.
