PianoAudit — Is it in Tune? のアプリ分析 10月1日

Is your piano in tune? PianoAudit listens while you play each key, plots the result against the piano's ideal tuning curve, and tells you in plain language whether it needs tuning, from "in good tune" to "needs a pitch correction." There is no account and no advertising, and the full diagnostic is free. HOW IT WORKS 1. Set your phone on the piano and play each key. 2. Watch each note appear on the graph as you play. 3. Read the verdict, a recommendation with the numbers behind it. A full measurement takes a few minutes. About 20 keys is enough for a confident verdict. Playing all 88 gives the most complete picture. WHAT THE FREE VERSION INCLUDES • Measurement of all 88 notes, with pitch detection designed for pianos • The tuning curve: your piano plotted against its own ideal stretch curve, with the acceptable range drawn in so you can see whether a tuning is in range • A plain answer, such as "In good tune. No tuning needed now." or "A pitch correction and a full tuning are recommended." • A PDF assessment of your piano that you can share • One piano with two saved measurement sessions WHY IT MATTERS Pianos drift out of tune slowly, and day to day you adapt and stop hearing it. Seasonal humidity swings pull the pitch up and down. A piano left too long can drop far enough that it needs extra work (a pitch raise) before it can hold standard pitch again. PianoAudit shows where your piano stands, so you know when to call your tuner and when you can wait. FOR PIANO TECHNICIANS PianoAudit Pro produces a report you can hand to the customer: • Before and after tuning reports: a one-page PDF with your business name, overall pitch, and average deviation • A record of the pitch raise, showing the customer what was done and why • A measurement takes about 90 seconds. Play a quick chromatic scale, or leave it running while you check unisons • Works alongside any electronic tuning device, or your ears • Unlimited pianos and unlimited session history Prospective clients can measure their piano with the free app and send you a screenshot, so you can quote the pitch correction before the appointment. UPGRADES • Plus (one-time purchase): up to two pianos, unlimited session history, and several sessions compared on one graph • Pro (subscription or lifetime): everything in Plus, unlimited pianos, and before and after customer reports with your business name The app and its tiers are the same on Android and iPhone, and exported piano files open on either platform.
