Der Geräuschpegel hat viel zu niedrig angezeigt selbst bei extremer Lautstärke. Das Geld aus dem Fenster geworfen 🤷🏻‍♂️ ### 2/5 — Brief Intro would be helpful *2023-09-07* Doesn’t tell you anything about how to use it or how it works leaving you confused if it is doing what it was supposed to be doing and if you are doing what you are supposed to be doing to find out what what you want to find out! Quite confusing yeah…!! ### 1/5 — Don’t buy this app until update *2023-03-04, version 2.0* I’ve purchased this app 5 years ago and was good working but currently does not work correctly. Seller - please fix bug and update this app. ### 4/5 — Love It *2023-01-12* As good as a $100 sound meter for my use. Just wish the screen would auto rotate on my iPad. ### 2/5 — ios 16 breaks the app metrics *2022-12-23, version 2.0* very recently the app is no longer calibrated properly, tried reinstalling and looking for settings but cannot find a solution, purchased awhile ago; previously worked well ### 2/5 — Unable to mesure sound level *2022-11-21* Unable to mesure accurately sound level because IOS 16 automatically adjust sound level on the microphone… ### 1/5 — Ridiculously inaccurate *2022-11-04* Don’t trust the readings at all. It’s way off. ### 5/5 — DB Meter *2022-09-01, version 2.0* Very helpful when you need it. ### 5/5 — In flight path. *2022-06-21, version 2.0* Just being curious so I downloaded the app. Awesome, I use it all the time just for fun. ### 5/5 — Used this app for last 4 years. *2022-04-30* Needed this app to form risk assessments. Although not calibrated, it’s not far off the mark and gives a pretty good basis to go on. Really easy to use and can switch to C weighted if required. Although retired now, I still use it on occasions. ## Frequently asked questions about dB Decibel Meter ### What does the dB Decibel Meter app do?
