Piano Tuner Pro vs X

Piano Tuner turns your iPhone into a precise, fast, and genuinely usable tuning tool — built around how pianos actually work, not just generic chromatic tuning. Most pianos have more than one string per note: two in the middle register, three across the treble. If those strings drift apart, even by a few cents, the note loses its bloom and starts to beat. Piano Tuner is built for exactly this. Switch between 1-, 2-, and 3-string modes and watch each string land on pitch independently, so your unisons ring clean. REAL-TIME PITCH DETECTION A responsive autocorrelation engine listens through your mic and locks onto the fundamental in milliseconds. The note name and octave appear instantly, with live frequency in hertz right below. A DIAL YOU CAN READ AT A GLANCE A smooth, weighted needle sweeps across a −50 to +50 cent arc. The whole readout shifts color as you close in: amber when you’re off, red when you’re sharp, and a clean teal the moment you’re within a few cents of perfect. No squinting at tiny numbers mid-tune. CENTS OR HERTZ, YOUR CALL Tap once to switch the readout between cents and hertz. Work in cents for fine unison matching, or hertz when you want the raw frequency. The dial and per-string panel follow whichever you choose. PER-STRING UNISON PANEL Set the app to 2 or 3 strings and each one gets its own live deviation bar. Bring the first string to pitch, then match the rest to it by eye — no mutes, no guesswork, no beating. CLEAN, FOCUSED, DARK A calm dark interface with a single bright “in-tune” cue keeps your attention on the one thing that matters: the pitch. Subtle haptics confirm every tap. Portrait-locked and distraction-free. WHO IT’S FOR • Piano owners keeping their instrument in shape between professional visits • Students and teachers checking pitch by ear and by number • Technicians and hobbyists who want a fast reference in their pocket • Anyone tuning a multi-string acoustic instrument No accounts. No clutter. Just open it and tune. Note: Piano Tuner uses your device microphone to detect pitch. It works best in a quiet room.

Your Shakuhachi Practice Companion. Your Teacher/Master transmits the tradition. You practise. X-RYŪUN accompanies you between lessons. Start by calibrating your shakuhachi. Then work on your sound and long tones — Robuki — on RO or other notes, so that repetition helps build your playing rather than gradually reinforcing mistakes. Play your pieces. Record your own performance — or analyse the performance of any other player — across 100 criteria organised into 3 pillars: Sound Physics, Psychoacoustics and Japanese Aesthetics. Compare interpretations, discover what brings them together and what sets them apart, understand what needs further work, and focus your practice on what can genuinely help you progress. X-RYŪUN brings together the practice tools of ROBUKI TRAINER and the analytical capabilities of SHAKU EVAL in a single environment. With respect for the lineages and traditions through which shakuhachi has been passed down, X-RYŪUN accompanies your practice between lessons with your Teacher/Master.
