I use this app all the time for ringing out microphones, measuring SPL at concerts and in my car, with home theater setups, tuning subwoofer boxes, calculating the idle on my motorcycle... I could go on.
There was recently an update that caused the app to crash on my 5s running 12.4.8. I emailed the devs and received back a notification of a fix and scheduled update within minutes. And so I am here to write a review.
The best part of this app that I haven’t seen other apps do is the ability to save snapshots of frequency spectrum, to adjust the window function width, and simultaneously output different noise while capturing the input response. Super handy.
This app and service are worth every penny and should have higher reviews. Low reviewers don’t know what this app does or how to use it.
