Works beautifully!

Easy to set, very convenient button panel for popular frequencies, big adjustment wheel, serviceable but demonstrative oscilloscope. Also it sends over an AirPlay connection.

As a novelty, it’s pretty neat. As a working tool I see two things that would be helpful on this app:

1) A button to give a 440 Hz sine wave (A below middle C on the piano). This is the note most musical instruments use to tune.

2) Some way to more precisely tune to the frequency desired. As it is, when I use the slide I can only get close to what I want, and when I lift my finger from the screen the frequency changes.

This is an important tool

I use it as a tool for giving me a tool for Alzheimer’s. Seems to help,
