## What is GTuner?

Tune your guitar fast with a clean, accurate tuner that just works.

GTuner listens through your iPhone's mic and shows exactly which string you're playing and how to bring it into tune with a big note display, a smooth needle meter, a precise cents readout, and a satisfying green "in tune" lock. A photo-real guitar headstock lights up the string you're tuning, so you always know which peg to turn.

Everything runs entirely on your device. The mic is never recorded, and nothing is ever sent anywhere — no account, no ads, no tracking.

FEATURES
• Automatic string detection — just play, and GTuner finds the string
• Tap any string to tune it manually
• Cent-accurate pitch detection with a clear, responsive meter
• Guitar-headstock visual that highlights the active string
• Built-in metronome — adjustable tempo, tap tempo, time signatures, accented downbeat
• Clean, distraction-free design

Standard, Drop D, and Half Step Down are free forever — along with the full tuner and metronome.
