PianoMeter is a piano tuning app that will transform your device into a professional quality electronic tuning aid.
NOTE
The "free" version of this app is primarily for evaluation, and it only allows you to tune notes on the piano between C3 and C5. To tune the entire piano you will need to buy an upgrade through an in-app purchase.
What makes PianoMeter unique
Unlike regular chromatic tuning apps that simply tune to a pre-calculated equal temperament, this app actively measures the tonal characteristics of each note and automatically calculates the ideal “stretch” or offset from equal temperament. In other words, it creates a custom tuning for your piano with the best compromise between intervals like fifths, fourths, octaves, and twelfths, the way aural piano tuners do when fine-tuning.
Functionality and pricing
There are three levels of functionality: a free (evaluation) version, a paid "plus" version with basic tuning functionality, and a "professional" version with features geared towards professional piano tuners. The extra functionality is unlocked through one-time in-app purchases.
The Free version includes the following functionality:
• Tuning functionality for the mid-range of the piano only
• Automatic note detection
• Ability to measure each note on the piano to see how its current tuning compares to the ideal tuning curve (see if a piano is roughly in tune)
• Swipe in the graphing area to show a live frequency spectrum or the inharmonicity of measured notes.
Upgrading to "Plus" adds the following functionality:
• Tuning functionality for the entire piano
• Tune to frequency standards other than A=440
• Tune to historical or custom temperaments
• Calibrate device to an external frequency source
Upgrading to Professional unlocks all features of the "Plus" version, plus the following:
• Save and load tuning files, so a piano doesn't need to be re-measured each time it is tuned
• Pitch raise mode that calculates overpull for an initial first pass "rough" tuning (for pianos that are extremely flat)
• Custom tuning styles: create a custom tuning curve by adjusting interval weighting and stretch
• Access to all future features and enhancements
Upgrade costs:
Free to Plus (approximately US$30)
Free to Pro (approximately US$350)

This app requires permission to access the microphone on your device and permission to read and write files.

I tried using PianoMeter as a beginner tuner, only to find that its inharmonicity calculations are not correct in the least bit. The bass especially is not even close to being in tune. I’ve had to tune aurally rather than use this app. I tested this by comparing the app to my Yamaha digital piano on the “grand” setting, and the app said C1 was 30 cents sharp, despite Yamaha’s expertise in making a tuned digital grand piano. I’ll be abandoning this app in favor of something that actually sounds good.
Well designed and easy to use!
This app is exactly what I needed. The first time I used the app I was a little confused by the interface to begin using the tuner but it wasn’t so hard to figure out. Once I made a new project, the visuals were stunning and it did exactly what I needed it to! 5/5 stars
app needs a update for mac os sonoma users
installed this app on my computer worked the first day then it stopped working after i did the updates to my computer i have this app on another device and it works flawlessly just wanted to have it on a larger device when it says it will work for my laptop
First Time Tuning
I've been interested in tuning my piano for some time. I had been doing a lot of reading and YouTube videos and came across this app. I downloaded it to my iPhone and updated it to the paid version. I ordered a tuning hammer and mutes. The day they arrived in the mail I told my wife, "Well, here goes!" I couldn't be happier with the results! As others have said, my first tuning took about 5 hours. The high notes were particularly challenging. But when I played it for the first time I knew I had made the right choice. The evaluation of the harmonics and calculating the tuning curve that this app does was significant to the quality of the tune. Great work, developers!
Piano hasn't sounded this good in ages!
Setting the temperament so cleanly wasn't even possible with my concert-grade stroboscopic tuner. This is a phenomenal professional-grade tuner, just like it says on the tin.
Excellence in customer service
I have been using this app for the 4 months and truly appreciate its functionality. I had a license issue after an iOS update the was quickly resolved by the developers. I highly recommend this app.
Way better than other piano tuning apps
I tried every highly rated piano tuning app I could find and this one is by far the best. I recommend watching the video on their website to see all the features.
Excellent program
I am a professional piano tuner and have used TuneLab since 2002. I tried PianoMeter for the first time today and loved the result! The pitch raise feature worked very well — I look forward to using it again on a bigger pitch raise. The final result was spectacular. I especially like the very quick response when I change notes. Much faster than with TuneLab, and you can switch to ANY note. Very cool.
This is the app to get, + some precautions
Tuning a piano is NOT like tuning a guitar, violin or any other instrument. This is a tool specially made for tuning uprights and grands and does a great job at being a tuning aid. Before you attempt to tune your piano PLEASE be familiar with the subject of tuning as there are many subtleties to it. When using the app, tune octaves starting from A4 with the tuning curve unlocked. Every piano is different and you must establish the tuning curve by ear rather than assuming the default works with you. Even as you are tuning - be sure to always check the extremes of the piano with your ear. You get out of this app what you put into it. Have fun!
Worked then didn’t
Works great until I updated to IOS 15.1.1. Now it flickers and can’t use it without getting dizzy. Please fix.
