About this app

Piano Tuner PT1 is a professional-grade piano tuning tool, built for technicians who demand extreme precision. With over a decade of development, PT1 offers accurate pitch detection across all 88 keys, octave stretching controls, historical deviation graphs, and support for alternate tunings. Designed with an advanced pitch recognition engine, it delivers real-time analysis of frequency, deviation, and tuning stability - helping you achieve concert-quality results every time. Reliable, accurate, and built specifically for the complexities of piano tuning. Unlike general-purpose tuners, PT1 is optimized for the unique harmonic structure of the piano, ensuring you can confidently achieve precise, stable, and musical results across the entire instrument. Professional-Grade Precision At the heart of PT1 is an advanced pitch recognition algorithm capable of detecting fundamentals and partials in real time. It delivers instantaneous readings of pitch frequency, cent deviation, and tuning stability - giving you the information you need to bring every note to perfection. Key Features • Full 88-Key Range Accurately tune every note, from A0 to C8, with precise pitch analysis. • Octave Stretching Settings Adjust stretch tuning values to follow the tuning curve as per your preference. • Historical Deviation Graph Track pitch stability over time with an intuitive graph that confirms the reliability of your work. • Alternate Tunings Supported Flexibly set A4 to values other than 440 Hz for Baroque tuning, orchestral variations, or client-specific requests. • Real-Time Accuracy With instantaneous feedback, you’ll always know exactly how close you are to the target frequency. Built for Piano Technicians PT1 is more than just a tuner - it’s a professional instrument analysis tool. Whether you’re preparing a grand piano for a concert stage or maintaining uprights in practice rooms, PT1 adapts to your workflow and supports the detail-oriented precision your craft demands. • Trusted Worldwide: Used by professional piano technicians across diverse environments. • Proven Reliability: Over 10 years of development, testing, and refinement. • Clean and Intuitive Interface: Designed so you can focus on listening and adjusting, not navigating complex menus. Important Note Piano Tuner PT1 is intended for professional piano tuners and technicians. It provides powerful analysis tools but requires prior knowledge of piano tuning methods. It is not a casual “auto-tune” app for beginners. Why Choose PT1? • Professional-grade accuracy across the full piano range. • Flexible tuning with octave stretching and alternate standards. • Visual confirmation of tuning stability through deviation graphs. • A trusted tool developed specifically for the needs of piano technicians. With Piano Tuner PT1, you can tune with confidence, precision, and reliability - every single time.
