## Description

A–440 Tuning Fork provides simple, immediate tuning with a single tap. It generates a tone quickly and lets you set up a Siri Shortcut inside the app, then add the shortcut to the Home Screen, Dock, and Shortcuts Widget for instant access. Frequency is adjustable from 435 Hz to 445 Hz (A–440 by default). It’s also handy on iPad with Slide Over for convenient control. The 14-day trial is free via a no-cost, obligation-free App Store purchase; after the trial ends a license is required to continue.
