"notes": "ChromTuner is now on your Apple Watch! • New app for Apple Watch — tune hands-free right from your wrist: the same precision engine, a live string indicator that lights up as you move across the neck, and a haptic tap the moment a string locks in. Turn the Digital Crown to switch tunings. • New tuning: Open D joins the collection — 17 tunings total. • Smarter calibration — \"detect\" now works with any held note, not just an A. • The display now clears properly during loud, unpitched noise instead of holding the last note. • VoiceOver now speaks the live tuning reading on iPhone and Apple Watch. • Assorted fixes and polish throughout. Works free on Apple Watch, just like on iPhone: chromatic, Standard E and Drop D included. Pro unlocks everything, everywhere — one purchase, forever."
