Thank you for using Audiquo Tuning Fork. We are always trying to improve it to make it more convenient, more useful and, of course, more beautiful! In this update, we have updated the iPhone app. We have added an in-app volume control and doubled the capacity of the Palette to eight pitches. You can now lock the Palette so that you can keep a set of pitches there for fast access. To do all this, we have moved the preferences up to the top right to make space for all these extras. We hope you continue to enjoy using Audiquo Tuning Fork.

Recent pitches -- up to four -- are now stored on screen for quick access and playback.

Bug fixes -- better handling of changes to the audio output configuration.

Thank you for using Audiquo Tuning Fork! Here is what's new in this update: A small user interface enhancement: the Play/Pause button is now simply a Play button. Now, if you tap Play while a pitch is already playing, the pitch starts to play again, just like when you tap a tuning fork. You can stop a pitch by tapping on its original position on the circle. It will remain the currently-selected pitch. Tapping again will deselect it and it will return to its original position on the circle. The Double Tap gesture plays the currently-selected pitch -- available on supported Apple Watches running watchOS 26 or later. A "progress" circle now tracks the pitch while it is playing. A bug is fixed on iPhone which paused play if the app was closed while a pitch was playing -- now the pitch plays to completion. Some improvements were made to Bluetooth playback from iPhone. The “Newton” theme has been renamed “Newton-Jameson”: D.D. Jameson (1844) extended Newton's original seven-pitch color scheme to all twelve pitches in the chromatic scale. Some colors have been updated to match the Newton-Jameson scheme. Layout, notation and typographic corrections and updates are included.

Audiquo Tuning Fork is now on iPhone as well as on Apple Watch! Tones are more realistic, decaying after about seven seconds. Add compatibility for new Apple Watches. Minor updates.

• A major update with an all-new user interface based on the well-known Equal-Tempered Chromatic Circle. • All 24 pitches in Octaves 4 and 5, from C4 to B4 and from C5 to B5. • Four music notations: Scientific, Fixed-Do, German and Helmholtz. • Tap the center to switch quickly between sharp and flat notation. • Plays in Silent or Theater mode. • Four new color schemes: two based on Newton's colors and two monochrome schemes. • A new icon reflects the use of the equal-tempered chromatic circle with Newton's chromatic colors. • Please note that audio, e.g. from the Music app, can no longer be played in the background while Audiquo Tuning Fork is playing a pitch.
