## What is Sisco's Guitar Tuner?

Sisco's Guitar Tuner is a free guitar tuner app built for acoustic and electric 6-string and 12-string guitars. Tune automatically, select strings manually, choose popular alternate tunings, create and save your own custom tunings, play continuous drone notes, and check guitar intonation in one focused app.

TUNE YOUR WAY

• Auto-Advance Mode: Play the indicated string and the app listens through your device's microphone. When the string reaches the selected in-tune range, the tuner automatically advances to the next string.

• Manual Mode: Tap any tuning peg or string to hear its reference note, then tune by ear or use the live pitch display.

• 6-String and 12-String Guitar: Switch instrument layouts for standard six-string guitars or full twelve-string guitar tuning.

ALTERNATE AND CUSTOM TUNINGS

Quickly select commonly used guitar tunings, including:

• Standard
• Drop D
• Whole Step Down
• DADGAD
• Open G
• Open D

Create your own tuning presets and save them for later. A half-step-down option can lower every target note by one semitone, making it easy to use E-flat tuning or transpose an entire saved setup.

DRONE NOTE PLAYER

Play a continuous reference note for tuning by ear, ear training, vocal or instrumental pitch practice, and improvising over a steady tone. Select the note you need and let it continue while you tune or practice.

GUITAR INTONATION CHECK

Use the included intonation tool to compare an open-string pitch with the same string played at the 12th fret. Capture both readings and compare them to evaluate whether the fretted note is sharp, flat, or aligned with the open string—useful when checking a guitar setup.

ADVANCED TUNER SETTINGS

Personalize how the tuner responds:

• Adjust the A4 reference frequency
• Set microphone sensitivity
• Choose the in-tune window in cents
• Fine-tune detection behavior for your instrument and environment

CUSTOM WALLPAPERS AND PHOTO BACKGROUNDS

Choose from included tuner wallpapers or select a photo from your own library. Adjust the background blur for a cleaner depth-of-field effect while keeping tuning information easy to read.

Sisco's Guitar Tuner gives guitarists a practical tuning tool for everyday practice, alternate tunings, 12-string setups, custom tuning presets, drone-note practice, and basic intonation checks.
