does not show frequency, only decibels which would be fine if I didn't search specifically for frequency monitor so they've obviously included that in their SEO keywords illigitimately. It is also covered in obtrusive ads beyond the norm of a free app.

Some ads are there, but manageable. Overall the app does the job, better than the other one i tried.

Using this app to record train horn sound levels. You can use your camera and video as you record sound levels. Excellent.
