Tuner - gStrings is a chromatic tuner app that measures sound pitch and intensity to help you tune any musical instrument with accuracy. Whether you play violin, viola, cello, bass, guitar, piano, wind instruments, or sing, this app delivers the precision you need for professional-quality tuning.

Get started with multiple built-in instruments and standard tunings covering guitars, stringed instruments, and more.

Advanced players will appreciate support for user-defined custom temperaments, orchestra tuning mode for shifting and redefining tone frequencies, and a built-in pitch pipe for reference. These features make the app useful for both everyday practice and specialized performance scenarios.

The interface displays pitch detection in real time, making it straightforward to dial in accurate tuning on any instrument. Musicians at every level—from beginners learning their first instrument to experienced players working with unconventional tuning systems—can rely on this tool to stay in tune.
