Standard Tuning
E A D G B E. That's it. No confusing menus, no alternate tunings to accidentally select. Just the tuning 99% of guitarists use 99% of the time.
Real-Time Pitch Detection
Advanced autocorrelation works great with guitar's rich harmonics. See exactly how many cents flat or sharp you are, instantly.
Reference Tones
Not sure what the string should sound like? Tap any string button to hear the target pitch. Learn to tune by ear.
Haptic Feedback
Feel when you nail it. A satisfying tap tells you the string is in tune — no need to stare at the screen while you adjust.
Clear Visual Feedback
Big, bold note display with a visual gauge showing flat, sharp, or in tune. Green glow when you hit it. Works great in any light.
