## Description

**G-Tuner** is a fast, accurate tuner for guitar and other string instruments. Its microphone-based pitch detection delivers stable readings in noisy environments, while the simple interface shows the target note, pitch accuracy, and tuning status at a glance. Animation and alert sounds help confirm when each string is in tune.

Adjust the reference pitch from 390–490 Hz, use DOWN/CAPO settings from -5 to +7 frets, and tune instruments including guitar, bass, banjo, mandolin, and ukulele. Optional paid features add chromatic and high-precision modes, detailed pitch information, faster in-tune detection, alternate and custom tunings, and support for up to 10 strings. G-Tuner offers ±0.1-cent accuracy at 440 Hz across an E0–E7 range.
