Perfect Guitar Tuner

A practical tuner for string players

Perfect Guitar Tuner listens through your phone’s microphone and helps bring strings to the intended pitch. It suits guitarists who want a quick check at home, before rehearsal, or between songs, without carrying a separate tuner. It is designed for acoustic and electric guitar, bass, and several other string instruments.

More than standard guitar tuning

The app includes common alternate tunings as well as presets for other instruments. That makes it useful when a song calls for a different setup, or when you switch between guitar and another stringed instrument.

• Standard guitar tuning
• Drop D, Open D, Open G, and Open A
• Four- and five-string bass
• Ukulele, violin, viola, banjo, and other presets

Choose how you want to tune

Automatic mode detects the note being played and indicates how close the string is to pitch. Manual mode lets you select a target note yourself, which is useful for deliberate alternate tunings. A play mode provides reference tones so you can tune by ear or practise recognising string pitches.

Reference sounds are based on recorded instrument tones rather than only synthetic beeps. You can also adjust the reference pitch, customise the string set, and choose between note-naming conventions used in American or European systems.
