Top 10 Best Piano Tuning Software of 2026

TuneLab is a professional-grade piano tuning software designed specifically for piano technicians, utilizing microphone input to provide precise pitch detection and real-time visual feedback for accurate tuning. It excels in aural-guided tuning, allowing users to set custom temperaments, apply stretch curves, and fine-tune unisons and octaves with spectrum analysis of partials. The software supports everything from pitch raising on old pianos to concert-level tuning, making it the gold standard in electronic tuning instruments (ETIs). With decades of refinement, it remains the top choice for serious tuners worldwide.

Reyburn CyberTuner is a professional piano tuning software designed for expert technicians, utilizing microphone input to measure piano tones and generate precise tuning recommendations. It employs patented Pure Tuning Curve (PTC) technology to create musically optimal tuning scales with customizable temperament, stretch, and partial tuning capabilities. The software supports pitch raising, fine tuning sessions, and advanced features like binaural beat detection for enhanced accuracy.

Veritune is a professional-grade piano tuning software available primarily as an iOS app, leveraging advanced spectrum analysis for precise electronic tuning of pianos. It supports customizable stretch curves, real-time frequency detection via microphone, and tools for fine-tuning partials and intervals. Ideal for tuners seeking high accuracy, it combines aural and machine-assisted methods to achieve optimal intonation across grand and upright pianos.

Accu-Tuner is a professional-grade piano tuning software developed by Sanderson Industries, designed specifically for piano technicians to achieve precise tuning using a computer's sound card and microphone. It provides real-time frequency analysis, visual tuning indicators, and support for custom temperaments, including Sanderson's proprietary fine-tempered scales and stretch algorithms. The software excels in delivering accurate partial-based tuning guidance, making it a reliable tool for concert-level piano preparation.

PianoMeter Pro is a professional piano tuning software for iOS, iPadOS, and macOS, delivering high-precision tuning through 96kHz audio sampling. It supports fine tuning, pitch raising, temperament setting, and custom stretch curves, with tools for aural verification and fine touch response measurement. Designed for piano technicians, it combines visual strobe tuners, partial analysis, and advanced customization for optimal instrument intonation.

Peterson Strobe Tuners software, primarily through the iStroboSoft apps for iOS and Android, converts mobile devices into precision strobe tuners using the phone's sensors for pitch detection. It excels in visual strobe pattern feedback for ultra-accurate tuning down to 0.1 cents, with pre-configured 'sweetened' temperaments tailored for piano inharmonicity and octave stretching. While versatile across instruments, it's particularly valued by piano tuners for fine adjustments during professional setups.

TonalEnergy Tuner is a versatile mobile app (iOS/Android) functioning as a chromatic tuner, metronome, and tone generator, with precise pitch detection ideal for piano tuning tasks. It offers cent-accurate readings, adjustable reference pitches (415-466 Hz), and a spectrum analyzer for harmonic visualization, enabling tuners to assess partials and deviations effectively. While not piano-specific, its professional-grade accuracy and portability make it a strong contender for both amateur and pro piano technicians.

Cleartune by Cocologics is a mobile app tuner for iOS and Android that uses high-resolution spectrum analysis for precise instrument tuning, including pianos via partial-based detection. It supports fine adjustments down to 1/100th of a cent, customizable temperaments, and real-time visual feedback for professional results. While versatile for various instruments, its piano tuning capabilities focus on accurate partial matching rather than automated stretch curves found in dedicated desktop software.

MeldaProduction MTuner is a free VST/AU/AAX plugin that functions as a precision tuner and spectrum analyzer, capable of detecting pitch and frequency for instrument tuning, including pianos, in a digital audio workstation environment. It displays real-time spectrum views, cent deviation, and supports custom temperaments for accurate note adjustment. While effective for fundamental frequency tuning, it lacks specialized piano tools like stretch curves or unison partial analysis typically used by professionals. Overall, it's a versatile analysis tool repurposed for piano tuning by musicians and hobbyists.

Voxengo SPAN is a free, professional-grade real-time FFT spectrum analyzer audio plugin that displays frequency content, peak levels, and stereo correlation, which can be repurposed for piano tuning by visually identifying note fundamentals and harmonics. It excels in high-resolution spectral analysis but lacks dedicated piano tuning tools like automatic pitch detection, keyboard mapping, or temperament presets. Users must route piano audio through a DAW or compatible host for analysis, making it a general-purpose tool rather than a specialized solution.
