Need update

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.

Very flexible

It would be even better if it could input and output to emails.

Fun & Easy Educational Tool

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.

Easy to use but need to improve accuracy

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.
