## TuneLab Piano Tuner Description
This app is for professional piano technicians. This is a professional tool that produces a custom piano tuning for any piano. It is part of the TuneLab line of piano tuning programs for smartphones, tablet computers and laptops that piano technicians have been using since 2001.

Notable features:

* Measures and uses inharmonicity of the piano to construct a custom tuning.
* Provides an over-pull mode for more accurate pitch-raises.
* Can store hundreds of tuning files for individual pianos.
* Tuning files can be stored locally and in the Cloud on Dropbox. 
* Provides many historical temperaments for period music.
* Switches notes automatically when you play the next note.
* Provides a strobe-like Phase Display for fine-tuning.
* Provides a versatile frequency spectrum display.

TuneLab lets you customize a tuning by sampling the inharmonicity for a few notes of the particular piano. You can choose the kind of tuning stretch you want by specifying different intervals for the bass, the treble, and the mid-range of the scale. These intervals can be octaves, 12ths, double octaves, etc. Good defaults are in place if you are not sure which settings you prefer.

After a custom tuning has been created from inharmonicity measurements you can store this tuning by name. The next time you need to tune that piano, or one very much like it, you simply load that same tuning file and start tuning. There is essentially no limit to the number of tuning files that you can store. TuneLab comes with some sample tuning files and an "Average" tuning file so you can start tuning right away without bothering to measure inharmonicity.

TuneLab covers the normal piano range from A0 to C8 (88 notes). The automatic note-switching feature makes it possible to enjoy hands-free operation. There is also easy one-touch manual note switching.

TuneLab has two different displays that are visible at the same time. One is the strobe-like Phase Display. This is a band where black squares move left or right depending on whether the note is sharp or flat. Tune the note to make the pattern stop moving. The other is the Spectrum Display. This is a graph of the frequency spectrum around the desired note that shows a peak in the audio frequency spectrum for every pitch present in the sound. The object in using this display is to tune the note until the peak in the graph is positioned at a central red line. The Spectrum Display makes it possible to do a rough pitch-raise without mutes since each string of a unison produces its own peak in the graph. Having both the Phase Display and the Spectrum Display visible at the same time gives you a more complete picture of the tuning than any single spinner-type or needle-type display.  The Phase Display displays a selected partial at each note, but it can optionally display the tuning of up to four different partials at once in multi-partial mode.

## TuneLab Piano Tuner Reviews in United States

### ***-- "Okay but not my favorite"
Tune lab gets the job done with acceptable results. It is good to have as a back up and I really like being able to see the peaks for a pitch raise. I also own an Accu-tuner 4 and prefer using that over tune lab for fine tunings. The Accu-tuner beats tune lab every time on the quality of tuning and ease of use when fine tuning.
-- JFrank90, 2022-12-06

### ***** "Robert Treadway"
I've been using Tunelab for the IPhone for about two decades now and am very pleased with it. I have also used the more expensive programs out there and tho they are good they are not better quality.  Also, Tunelab has good support if you have any questions. Try that with Cybertuner(they want you to pay extra for any help). I recommend Tunelab over the others in price and equal quality of product.
-- Pianotunerman, 2022-11-07

### ***** "Fantastic"
I have been using TuneLab for over 5 years now. As a piano technician and tuner I highly recommend this app. It is simple to use and accurate as well as cheaper than many of the other professional piano tuning tools and/or software available.
-- EllhartConn8D, 2022-06-23

### *---- "Yes it works but …"
Years ago, i would have rated this a 4 star. The app works, yes. The tunings are good, not great but certainly decent. But no improvements have been made in years! The app still looks like something from the seventies and most importantly, requires (Yes REQUIRES) a dropbox account for file sharing. After all these years milking for money, the author cannot be bothered to add icloud syncing (which is not difficult, being a software dev myself). I don’t always have an ipad available, being able to go between ipad and iphone is a must for me. No i don’t want bloatware dropbox on my iphone/ipad.
-- joost4u, 2022-02-14

### **--- "Charged wrong price!"
After much consideration and advice from colleagues, I opted to purchase Tunelab to assist my aural tunings with difficult temperaments and stretches.  Throwing down $299.99 isn’t an everyday thing for me.  You can imagine my frustration when instead of being charged the displayed $299.99, I was charged $320.99 instead!  Unfortunately this means that my initial experience has left a poor taste in my mouth.  I feel cheated.  I’d like a refund for the difference.
-- PreacherManNC, 2021-03-31

### ***** "Extremely Useful"
I started tuning my pianos a couple years ago  (m&h aa, yamaha c5) and this tool has helped me immensely!  Calculating the stretch and inharmonicity really helped me have a solid starting point to work from.  In addition the phase display has helped my aural tuning by providing visual feedback to what I hear.  
I'm not a pro and I'm sure I don't take advantage of all its features but as an amateur this too is indispensible! 
My pianos sound better than they ever had and I learned loads of great acoustic theory in the process.  Well done!
-- Longmont CO, 2021-03-26

### ***** "A must have tool"
I have been a piano tuner for over 40 years. I started using Tune Lab 11 years ago and love it 
The most valuable thing about it is that I can tune even in extremely noisy locations with full confidence 
The most challenging situation involved tuning in a building full of noisy people. Pouring rain on a metal roof and concrete floor. The acoustics were so bad I couldn’t really even hear the piano. It would have been impossible to tune by ear but TuneLab saved the day. Thank you TuneLab
-- hooked on tunelab, 2021-01-29

### *---- "Help! I’m not a pro!"
Please let me return this. Never should have bought it without looking into it further. I’m not a seasoned veteran and can’t understand what the app is asking me to do.
-- Mocha Micah, 2019-09-07

### ***** "Great app"
I’ve been using TuneLab for about 15 years of my 40 year piano tuning career. I have some of the more expensive apps, but have come to sure TL more than the others because of its simplicity. It’s great for pitch raises also. I recommend it.
-- Asdf75, 2018-07-01

### ***** "For Professional Use"
I am a long time “by ear only” professional piano technician who started using TuneLab a decade ago just for experimenting.  This is not a “do it yourself” tuning app for pianos.  It is an excellent measuring tool for real piano technicians who already understand the fundamentals of piano tuning.  Everyone has their preferences, but it is in the same league as Verituner and CyberTuner, other pro apps in the pricing stratosphere.  It is especially useful for pitch raising and tuning in noisy environments.  I recommend it.
