The best free tuner app for guitar, bass, ukulele, violin or any other string instrument. A must-have tool in your guitar tool kit. Tune your guitar, bass or other instruments with the free n-Track tuner in two steps: it will automatically recognize the note you are playing and tell you if you need to lower (green bar) or increase (red bar) the pitch of the string. Audio spectrum provides visual feedback of the notes played by the instrument and displays a small arrow to highlight the harmonic whose pitch the tuner is tracking. For those who prefer to manually tune their instrument, the 'Tuning Fork' view allows you to play a reference pitch, 'A' (440 hz) or any other note you can select by dragging the slider frequency.
