Simple but it works

Easy to use, simple and it works.
The only way to make it better would be to add a way to choose where to save the csv files.
I don’t think I would pay for an app like this, it would need to have built in analytics and scheduling. But for a free app can’t ask for anything better.

Awesome

Thank you for the app! I am impressed with the micro adjustments from 0 to 50 and 0 to -50! It’s helpful when you want to hear loud sounds or quiet/faint sounds!

Where is the cvs file saved?

Can’t find the saved file.

Mic calibration

How do I calibrate the microphone? When I click the setting it just gives me a plus or minus adjustment. I don’t know how to use it.

Response from developer

The microphone on apple devices is quite accurate and unless you need a very precise measurement, you don't need to modify that setting. In any case to perform the calibration it would be necessary to make a comparison with a professional decibel meter. You can adjust the measurement in real time or save a csv file for later comparison.

Yup, works.

Simple, but does as intended.

Response from developer

Thank you very much for your rating and comment
