Easy Layout - Replaced Old Apps

I’m an Audio Engineer that services commercial installed AV systems. I use apps like this on the daily for testing, but haven’t found one that is ad free, no frills, and does what I need without paying an arm and a leg for, so I’ve been using old (developer gave up on) apps... until now.
Thanks for making this app!

One suggestion I have is somehow making adjustable variables when using “random”. would love to narrow down and set a group of frequencies and at an adjustable rate of time, but just an idea.

Nice easy to use app.

Easy to use app. Would give 5 stars if it would allow to use airplay to transfer the sound to my car stereo for testing. Seems to be only to use the internal IPhone speaker.
