Some button issues and small but annoying bugs I tried to check the ambient frequency to see if the neighbor was using the subwoofer to disturb me, but I was unsuccessful.

This free App is a quick & easy way to illustrate Fourier modes and even concepts like frequency & pitch. My thanks to the developer, Eisaku Nozu, for creating & sharing it.

App is very intuitive and free. It shows numerical values of frequency of peeks. However, the value is not super accurate. For example, the middle A sound is 440Hz. The app shows 441.4. And it’s happening on both my iPhone and iPad. So it’s very unlikely due to the microphone.
