Advanced Tuner

Advanced Tuner is a free guitar tuner and chromatic tuner that also handles bass, violin, ukulele, mandolin, viola and cello. Play a string, read the needle, done: tuning to the cent, with no menus in the way.

TEN TUNINGS, READY TO GO
• Guitar: standard EADGBE, Eb (half step down) and D (full step down)
• Bass, ukulele and mandolin
• Violin, viola and cello
• Chromatic mode for everything else: it finds the nearest note on its own

AUTOMATIC OR STRING BY STRING
Leave it in automatic and it follows whatever you play. Or pick a string and it holds it, so a fret buzz or a neighbouring string cannot steal the reading.

YOUR OWN TUNINGS
Drop D, open G, DADGAD, seven-string guitar, banjo, baritone ukulele. Name each string, set its frequency, save it. Up to 7 strings per tuning.

TUNE BY EAR TOO
Tap a string to hear it, recorded from the real instrument. Useful for a wind instrument, a voice, or anywhere a microphone struggles.

BUILT TO BE READ AT A GLANCE
• Neon needle with a green zone: inside it, you are in tune
• Live pitch trace, so you can see whether the note is steady or drifting, the honest test for bowed strings and for singers
• Frequency in Hz and deviation in cents, always on screen
• Screen stays on while you tune

Microphone access is required: it is how the app hears your instrument. Nothing is recorded and nothing is sent anywhere.
