Verdict
The clearest difference is monetization model: Decibel Meter Plus Pro at paid against Postage Stamp Camera's subscription. Decibel Meter Plus Pro also leads on ratings volume (81 vs 15) and device support (3 vs 1). Postage Stamp Camera's advantage is rating (4.0 vs 3.8). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Decibel Meter Plus Pro sells 1 one-off in-app purchase and Postage Stamp Camera sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
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.
Both ship on a similar rhythm, roughly every 2 months. Both last shipped on November 6, 2026.
