Introduction

A4tune is a guitar and violin tuner for Android, designed to tune your instrument extremely precisely and very efficiently using two displays: the strobe tuner at the top, the chromatic tuner at the bottom.

In tune: The strobe pattern does
not move, and the chromatic
view shows the tone.

You can switch between the violin tuner and the guitar tuner in the settings, or you can adjust the concert pitch frequency there.

A4tune is ideal for tuning your violin or guitar, and you'll really enjoy the sound of your instrument after tuning.
