Ad-free chromatic tuner with 0.1-cent display and 14 historical temperaments
A-Tuner is a full-featured, ad-free chromatic tuner for a wide range of instruments, from strings to winds. Its uncluttered display lets you focus on tuning and practice. Play a note and your device's microphone picks it up. A rotating indicator and bar show whether the pitch is sharp or flat, while the note name, octave, frequency, and pitch deviation appear at a glance. Pitch deviation is displayed in 0.1-cent increments, helping you make fine adjustments with confidence. The built-in tone generator can play the note of your choice, and the metronome is ready for everyday practice. You can also adjust the concert pitch, input sensitivity, in-tune tolerance, and display theme to suit your instrument and playing environment.
