Just a simple user... – Tone generator Review

I had a bit of trouble getting the app to work after upgrading to "ad-free". I wrote to the developer and received a prompt, civil response. I had removed the app, let it "sit in the cloud" for several days, then re-loaded it and it works as advertised. I was especially keen for this app to work as it seems to be the only tone generator that will produce frequencies above 20kHz. GREAT APP! WORKS AS ADVERTISED!! I cannot speak to the accuracy of the frequencies produced as that aspect isn't critical to my needs.
