Professional Tuner

Professional Tuner is a fast, stable and precise tuner built for bağlama (saz), guitar, oud, violin, kanun and many more instruments. Instead of reacting to the first attack of the string, it tracks the true fundamental frequency, so the needle stays steady and your tuning is reliable.

BUILT FOR BAĞLAMA
A multi-pitch detection engine listens to every string in a course (alt, orta and üst tel groups) at the same time and shows each one separately, so you can tune your bağlama course by course instead of string by string.
• Short-neck and long-neck bağlama, divan sazı, cura
• Bağlama düzeni, bozuk düzen, misket, müstezat and other common tunings
• Karar note selection: Move any tuning to a different karar (tonic) note while keeping its interval structure intact

ONE APP, MANY INSTRUMENTS
• Guitar: Standard, Drop D, Drop C, DADGAD, Open G
• Bass guitar, violin, ukulele, mandolin, banjo
• Turkish oud, Arabic oud and kanun
• Create your own tunings: Set the note, octave and frequency for every string, including microtonal tunings

PROFESSIONAL TUNING ENGINE
• Advanced pitch detection combining YIN, MPM and harmonic analysis
• Stable readings with octave-error correction and noise filtering
• Precise deviation display in cents with a clear "in tune" indicator
• A4 calibration: Set the reference anywhere from 432 to 446 Hz and every target frequency is recalculated automatically

LIVE ANALYSIS AND TUNING REPORTS
Every tuning session is saved automatically. Tap a session to see tuning quality, string/course balance, a pitch graph and per-string results in a single report.
• Live Analysis: Watch stability and confidence in real time while you play.
• String Analysis: Pluck and hold a string to measure its stability and drift over 5 seconds. Easily spot worn or freshly installed strings that won't hold their tuning.
• Pitch History: Follow pitch changes over the last few seconds on a graph and see whether the note settles.
• Expert Mode: Inspect signal strength, confidence and stability values in detail.
• Export your reports as PDF.

METRONOME
Practice with a precisely timed metronome. Use the built-in time signatures or add your own, and practice with different note values.

LEARN
