Audiquo Tuning Fork, for iPhone and Apple Watch, plays any one of the 24 musical pitches in Octaves 4 and 5. The pitches are from C4 to B4 in Octave 4 and from C5 to B5 in Octave 5. Pitches play and slowly fade away, just like a tuning fork.

Pitches are arranged on the familiar and intuitive Equal-Tempered Chromatic Circle.

To play a pitch in Octave 4, tap it on the Chromatic Circle. To play a pitch in Octave 5, long-press it on the Chromatic Circle. When a pitch is played, it moves to the center of the display. Tap where it came from on the Chromatic Circle to stop it and return it to its position on the Chromatic Circle, or use the Play/Pause button to control it.

On Apple Watch, tap the center of the display (avoiding the play/pause button, if present) to switch quickly between sharp and flat accidentals.

Audiquo Tuning Fork offers four attractive color themes and four music notations: Scientific, Fixed-Do, German and Helmholtz.

On iPhone, themes, notations and accidentals settings are accessible from the app screen. On Apple Watch, long press the center of the display to access theme and notation and accidentals settings.

Also on Apple Watch, you can add a complication to your watch face for faster access.
And you can add Audiquo Tuning Fork to the Smart Stack, from where you can control the selected pitch or simply open the app.

Whether you're performing, practicing, rehearsing or listening to music, Audiquo Tuning Fork can provide just the pitch you need, right there on your iPhone and Apple Watch, one tap away, instantly ready.
