Get this for free instead! ### 1/5 — Disappointed *2026-05-09, version 1.1* Developers clearly don’t care about this app anymore. You cannot use this app while playing audio at the same time. So the app is useless to me and many others who require it for this reason. Above all, after being notified 5 years ago, they have still not even bothered to correct the spelling of disturbing. And I think that says quite enough about the app itself. Long forgotten about and abandoned. ### 3/5 — Higher *2026-04-18, version 1.1* Seems higher than my other decibel meters. Good concept though. ### 5/5 — 啊啊啊啊 *2026-02-28, version 1.1* 啊啊啊啊 ### 5/5 — Great job *2026-02-21, version 1.1* Just what I needed ### 1/5 — Questionable security *2025-10-31, version 1.1* Why, when I start this up, would it ask to paste the contents of my clipboard? This was not something as a setting in earlier iOS so I think this is a bad sign for security and will definitely aboid this app ### 1/5 — Doesn’t work *2025-02-05, version 1.1* It doesn’t work half the time ### 4/5 — Magnifique *2024-07-15, version 1.1* Magnifique l'application à un différentiel de deux décibels avec mon sonomètre. C'est dommage qu'il n'y ait pas d'étalonnage car ça serait une super application. Et elle est gratuite ### 1/5 — No Star for No Workie *2024-07-04, version 1.1* No Star for No Workie ### 5/5 — Nice *2024-07-01, version 1.1* it is helpful because it shows the sound what it sounds like! ## Frequently asked questions about Decibel Meter Master ### What does Decibel Meter Master do?
