Both are free to download. Decibel Meter Ultra sells 4 in-app purchases, starting at $7.99 per 7 days. Markham Communicator asks for nothing beyond the download.
Decibel Meter Ultra holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Decibel Meter Ultra has 2.6K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 60% of Markham Communicator's written reviews are positive against 43% of Decibel Meter Ultra's, so the app with the better star average is not the one people write more warmly about.
Markham Communicator ships an update fortnightly, Decibel Meter Ultra every 10 days. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
