Comments on PianoMeter – Piano Tuner for Android

★★★★★ Kent V. Busse · Mar 15, 2022

Definitely professional quality. Initially equal to aural accuracy. By that I mean that if the meter shows within one-half cent, the unison sounds accurate, and if I tune aurally, the measurements fall within one-half cent. That means about equal accuracy either way. There are definite exceptions, especially in wound strings. There have been cases where aural tuning required me to set two wires one or two cents apart according to the meter. That's fair enough--the physical wires are imperfect. After 50 years of aural tuning, my most noticeable speed-up is that Piano Meter detects slippage immediately. When I tune an aural unison, if the "fixed" wire slips, both wires are flat, and I need to make beat comparisons to find the error. With Piano Meter, I can SEE the slippage while it is happening. Overall this makes faster and much more stable tuning. Next advantage is the calculated intervals. In aural tuning, "a little bit faster than" is not a precise quantitative standard. One gets a feel for how different the beat frequencies should be, but Piano Meter works it out over the whole piano. Proofreading with all my aural tests shows that Piano Meter makes a better end-to-end temperament and stretch than I do aurally. After 50 years of tuning (now 52) I have enough hearing loss to NEED the expert coaching that Piano Meter gives. Especially in the high and low extremes, this ETD brings me into the ballpark more reliably than aural estimation. Without Piano Meter, I might not be tuning pianos any longer. There are stretch choices in Piano Meter for those who do enough tuning to distinguish the results. I'm nearly retired now, and "out of the box" tuning with Piano Meter suit me just fine. I am probably making accommodations unconsciously. It would be interesting to tune a dozen pianos at each of several stretch settings, but I'm a little old for that now. Serious pitch raisings (more than 20 cents) are a miracle here. Piano Meter makes an almost perfect overfull so that my second pass is much faster because the wires don't need much touch-up. It validates the old rule I learned 50 years ago that changing pitch more than 20 cents (maybe even 10 cents) is faster in two passes than in one.

I've been a piano tuner/tech for 20 years. This app WORKS! It listens to partials and sets the tuning curve right every time! Highly recommend!

This is not worth 500 dollars. No way, I'd rather tune by ear or just pay to get it tuned 3 times

★☆☆☆☆ Jason Bray · Aug 11, 2023

Well, 3 years later, I had given up on the app because at some point it just goes haywire and can't hear pitches. I had taken up tuning my upright and the app was working fantastic, until I walked out to my other studio and tried it on my grand piano which it could not hear. I didn't think anything of it until this morning when I tried it again and the app had gone absolutely haywire, and you couldn't tune anything with it cuz it couldn't recognize where it was? Discouraged and disappointed.

Love this app! BUT - I got a new phone and can't figure out how to log in to my existing account. I've already paid, and it's not OK that I would have to pay again in order to use the services I've already purchased. I will add more stars to my review if/when this is resolved.
