#gtuner

GTuner is a fast, accurate guitar tuner for iPhone. It hears your guitar through the 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.

##Features#

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

##Tunings#

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

Unlock All Tunings ($4.99, one-time — no subscription) adds 12 more power and open tunings: Whole Step Down, Drop C#, Drop C, Drop B, Open G, Open D, Open E, Open C, Open A, Open D Minor, Open G Minor, and DADGAD.

##Support#

###Why does GTuner need the microphone?

To hear your guitar and detect pitch in real time. That's its only use — audio is analyzed live on your device and never recorded, stored, or transmitted.

###I bought "Unlock All Tunings" on another device. How do I get it here?

Open the tuning picker, tap any locked tuning to open the unlock screen, and tap Restore Purchases. The unlock is a one-time purchase tied to your Apple ID, so it restores for free on all your devices.

###Is the unlock a subscription?

No. It's a single one-time purchase. Pay once, keep all tunings forever.

###Which devices are supported?

iPhone running iOS 16 or later. A real device works best — pitch detection needs a live microphone.
