Waste of $

The app fails to perform as described. The alarm function does not work, and you can only monitor for a max of 5 min increments. The app was a good idea that was poorly executed.

Developer Response ,

Thank you for your comment. We had tested this app, and the alarm function works fine by flash the screen. In addition, we had added options to allow users to do measurement with unlimited time.

Not a ranked app but the best

I searched long to find a decibel app and stumped on this one and truly the best:
It gives you a 40s read to compute all the data information about the decibels Noise around you with map location recording video photo and annotation with history and dB plot in chart. Just missing the capability to print report cards and save to PDF - maybe next update?

Worthless $$$ app 👎🏻👎🏻

This app is really bad since it combining all data in one column I mean the date, time, location ...etc 👎🏻
Also it didn't provide summary chart 😡 USELESS APP

Developer Response ,

Dear sir,
The exported file is in csv format, and you should use some software like EXCEL to open it and divide the data.
