## Pianoscope Description
pianoscope turns your iPhone or iPad into the ultimate assistant for high-quality piano tuning — for professional piano tuners and passionate pianists alike.

Free two-week trial. pianoscope Standard & Pro are available as in-app purchases.


FOR PROFESSIONAL PIANO TUNERS

With the Pro edition of pianoscope, you can increase your precision and efficiency and make your work less strenuous. Measure the inharmonicity of an instrument at lightning speed, or accelerate the pitch raising of strongly out-of-tune pianos. With pianoscope Pro, you will meet the expectations of even the most demanding pianists.


HOW IS PIANOSCOPE DIFFERENT FROM OTHER PROFESSIONAL PROGRAMS?

Conventional programs determine the required stretch similarly to piano tuners working aurally. They start with a temperament octave and go outward from there with fixed intervals. The disadvantage is that you, as a tuner, have to determine which intervals are suitable for the partial structure of an individual instrument.
With pianoscope, you only have to decide which intervals should generally be as pure as possible and choose the appropriate tuning style. Through thousands of calculations — impossible for a human — the program finds a tuning curve that optimally satisfies your requirements.

Find more information at www.pianoscope.app/features/pro


FOR PASSIONATE PIANISTS

Are you frustrated that your piano soon loses its finely balanced sound after being professionally tuned? With pianoscope Standard and some practice, you can create high-quality tunings yourself. You don't have to train your hearing for years. All you need is a little hands-on skill and the courage to learn something new.

## Pianoscope Reviews in United States

### ***** "Best piano tuning app"
I HAVE USED EVERY PIANO TUNING APP. I TUNE 900 PIANOS A YEAR. THIS IS THE BEST ONE. DO NOT WASTE YOUR TIME AND MONEY ON ANYTHING ELSE.
-- tim980, 2026-05-23

### ***** "A Tuning Must-Have"
I have only used the 14 day free trial thus far, but it a couple of sittings my friend and I, with minimal experience, got my piano tuned beautifully!!! We tried tuning by ear, which seemed at first to work, but ultimately sounded a bit off... this gives you precise quality control, enabling you to tune down to the cent! I will say on some lower treble and bass strings the tuner jumps around quite a bit— not sure why, but I still feel it works great! I highly recommend! I have yet to purchase it... I think $100 bucks is a bit overpriced, but hey, the creator’s got to make money too, and how many people honestly purchase a tuning app? I think for me, the cost is definitely worth it— I mean, how much do piano tuners charge? I would not recommend paying all that money for the pro version... I did not see any of the pro features to be useful enough to spend that much... they are features not even professional piano tuners need.

### ***** "PRO LEVEL"
Amazing results with this software. Thank you pianoscope!!!
-- ThePianoTech, 2026-04-08

### *---- "Paywall"
I wish the app would be clear about its paywall. I get that it’s “professional” or whatever but at least make the actual download cost money.
-- I like potato it yummy, 2026-03-21

### ***** "Does exactly what it says, and well"
I never write reviews for apps but I'm so pleased with this one that I can't not. I'll mention I don't tune pianos as a job, I just tune my own to avoid paying for someone else to. Very intuitive, very precise app. I LOVE that you can chose specific non-TET tunings; I used Young well-temperament with pure octaves and my piano is super dialed in now. The key colors are beautifully subtle yet unmistakeable. Something that would have taken years to do by ear I was able to do in just over an hour. Super stoked to have found this app. Thanks devs!
-- Music gut, 2025-12-21

### ***** "😍Amazing🎹Tuner🥳"
Really love this tuner and was able to successfully a severely detuned [untuned for decade(s?)] upright I was gifted, despite it being my first time piano tuning - although I have decades of mechanical and multi-instrumental + mixing & mastering production under my belt. This app was clutch in pulling it off successfully. The pro features are amazing and I'd love to give 6+ stars for the automatically ending free trial in stark opposition to the dastardly auto-enrollment avaricious big companies do. I sincerely applaud the developer's integrity! 🙌 IMHO, the pro version is where it's at, but at 600$ it is steep and although I believe that's a fair price for how cutting edge the algorithm is, I would love to see an installment option; like if you could buy pro for a year (150$) and after 4 years that converts to the lifetime that would be awesome. I did just find out that if you buy the standard for 100$, you only pay the difference to upgrade to pro, so perhaps the pro sub works as described above? Idk I found out about the upgrade on their site forum but cannot find any info on how the sub works. Im gonna snag the standard version for now so I can tune up thru the winter seasons swings. Thanks again for making such a beautiful app. Happy playing y'all! 🎹 🎉 Love & Blessings! ❤️💛💚

### ***** "Great Product"
I had a piano tuner here 5 times.  He finally said find another piano tuner.  Got another piano who tuned the piano and it was out of tune again in about 2 weeks.

Finally I starting thing there must be a product that I can run from my iPad and found your product.  I used it for the 14 day trial and bought it.

About a year later, my piano is still in tune.  The next step for me was to trash the piano until I found pianoscope.

Thanks

### ***** "Great app without Spinner"
I love this program.because it is powerful, modern, clean and easy to understand. Straightforward to use. Some people dislike the whole 88 keys sampling…but that’s what I really like because the variety of the pianos. The only thing I feel lack of the spinner indicator because a lot of people come from other famous bands…if you want to attract more people you better provide them more familiar environmental interface with more neat features ….hope we may have option to pick what we favor indicator in the future ！
-- Tony Z, 2025-11-25

### *---- "Paywall"
Upon opening it forced me to accept the free trial but I can’t confirm whether or not it will charge me in the future.
-- LambChopDinner, 2025-10-09

### ***** "Great App, but…"
I absolutely love this app! Paying for the full version is 100% worth it, especially if you run a piano tuning business. However, it would be really nice if this was available for MacOS and not just IOS, I have a work computer and have to bring my iPad with me to clients places and it would be much simpler to have it all on the computer. Other than that, it’s amazing! 🤩
