GTune is a chromatic instrument tuner designed to function similarly to traditional hardware tuners. It automatically detects the pitch of the note being played and identifies the closest note within the Western musical scale. This intuitive approach makes it easy for musicians to quickly tune their instruments with accuracy and confidence.

The interface features a central display that resembles a classic electronic tuner, showing the detected note and an LED-style indicator to visualize whether the pitch is flat or sharp. This clear visual feedback helps users make precise adjustments in real time, enhancing the tuning experience for both beginners and experienced players.

For those seeking detailed information, GTune offers a text display that provides the exact frequency in Hertz and the note’s position within the Western scale. This includes the note name along with an offset in cents, allowing users to see how much the detected pitch deviates from the standard note. This level of detail supports precise tuning adjustments and a deeper understanding of pitch accuracy.
