Simple, effective tuning, without fuss.

A single tap is all it takes to produce a tone.
But save yourself the hassle of opening the App - set up a Siri Shortcut, directly within the App, and you're done.
Well, nearly ...
Why not take convenience to the next level, by adding the Shortcut to the Home Screen, the Dock, and the Shortcuts Widget?
Now you're really set!
Need to tune to A–443? No problem, the frequency is adjustable (435–445 Hz).
A–440 is also a great fit for Slide Over on an iPad, where the ability to start and stop the tone at will proves its usefulness.
