Tuning Note plays a sustained reference tone for any chromatic pitch from G3 to A5—the full range of the violin, with headroom above and below. Select a pitch, tap Play, and tune by ear. The tone updates in real time as you navigate, so you can move between notes without stopping and restarting. Features: • Swipe, tap, or use navigation arrows to move between pitches • Configurable A4 reference frequency (415, 440, 442, 444 Hz, or custom) • Tap navigation by half steps or a fixed interval—default is a fifth • Light, dark, and system appearance modes
