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.

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. -- Ilikecloudyweather, 2026-05-22 ### ***** "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! ❤️💛💚 -- 16849:! $€~jah, 2025-11-29 ### ***** "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 -- mike052351, 2025-11-26 ### ***** "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! 🤩 -- Micah Williams Music YT, 2025-09-15 ### ***** "Works Very Well!" I just finished my first tuning and it came out great. Much better than I expected for my first attempt. The inharmonicity curve that the app created for my piano seems perfect. It stretched the octaves more than they had been, and it sounds much better this way. Lovely intervals up and down the scale. Using the hammer got a little scary in one section where a few pins were tight and a little jumpy, but that went away as I moved up the scale, thank goodness. A tip for beginners: be very careful on the very high notes. This part is difficult. Keep striking the key repeatedly at a consistant volume so your phone can hear the pitch accurately. I found the strobe very useful in this section. In short, this is a very well written app. Bravo! I will definitely purchase. -- StarvingNYCDilettante, 2025-06-28 ### ***** "The best I’ve seen" Extremely impressive piece of work. -- Gavia00, 2025-06-26 ### ***** "Supports Chinese please" 🥹 -- Oversteers, 2025-05-31 ### ***** "Simply the best" I have used other electronic tuners, including some pretty sophisticated and expensive (professional) ones and yet after using Pianoscope the difference was clear from the first tuning. Notes around the tenor C3 area are more precise and the 3rds and 10ths are more even, but the main thing is the overall sound of my piano. It was quite an emotional response actually as for the first time since leaving the showroom, my grand piano sounded so full and wonderful that I was lost in playing it for hours. And yes, it seems to have held its tuning better than before, although I do spend quite a lot of time and care on it. I can thoroughly recommend this tuner. I particularly like the multi-display (strobe and line) ways you can check the tuning, and the option to change the display - very useful. I think pianoscope is the new benchmark for electronic tuners for sure. -- Wannadoo, 2025-04-04 ### *---- "Useless" I couldn’t get it to work. The documentation was obtuse It had me play every key on my piano and showed me where things were on a curve, but I never could get it to analyze the and show me which way it needed tuning -- Bozeman Boy, 2025-01-29 ### ***** "Grade A tuner" I have never reviewed an app before. However, this app deserves accolades by the bushel. As a professional musician I have been mostly disappointed with tuning apps throughout the years. Many don’t take into account things like intonation of different instruments and pro level ideals. I found this app from The Piano Doctor on YouTube and I was an instant skeptic. On opening the app I knew it was grade A. The UI was intuitive, it measured inharmonicity, and gave a graphical curve so I could visualize the initial dissonance. Giving me a good understanding of where my problem areas were going to be. The piano I was tuning hadn’t been tuned since 1986. And this app performed perfectly! Well done devs!!! -- Kane Somnus Nox, 2024-12-26 ### ***-- "app refuses to allow tuning" trying to tune a jaymar chime piano, but app stubbornly refuses to allow specific pitch ranges, only prebaked ranges. then it refuses to allow tuning of known notes if any it expects aren't available. so if the app doesn't hear a c3 either bc it's so far out it can't recognize it, or bc the mechanism or string is broken, it refuses to allow ANY a tuning to even begin. dumb, rigid gatekeeping for an otherwise promising app. please fix this annoying bug. it should just work with you telling it (or it recognizing) what pitch you're playing even for an instrument with only one note. please fix this stubbornness. -- snuzor, 2024-11-29 ### *---- "Ive had this app installed for 30 seconds and it expects me to make a purchase…." I dont want to start a trial for anything that I cant even see functioning first… -- Iamthereviewer, 2024-11-13 ### ***** "BEST tuning app" I did my first tuning with this app today. I got a wayyyyy more accurate tuning. I’ve tried so many different tuning apps. Very expensive ones and free ones. This one is top notch. This is now my go to tuning app. -- JohnnyPiano81, 2024-10-27 ### ***** "Great app" I tune at least 20 pianos a week with this app. I tune at major recording studios in Los Angeles with iconic artists on a weekly basis. This program is very efficient. Switched from another well known tuning app due to more precise pitch readings and just overall better sounding tunings. Very modern and easy to use compared to other tuning apps on the market. The technology behind it is up to date and not 30+ years old like other more expensive software. Pitch raise is very accurate. Also really like the optimize pitch setting to tune the piano where it is currently hovering around. Excited about upcoming releases. -- tim980, 2024-07-31 [View all Pianoscope reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Pianoscope In-App Purchases | Item | Price | |------|-------| | Pro Monthly Subscription | $17.99 | | Unlock Standard | $99.99 | | Pro Annual Subscription | $169.99 | | Unlock Pro | $599.99 | | Upgrade from Standard to Pro | $499.99 | ## Pianoscope Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Grossing | Belarus | Music | #53 | | Top Grossing | Czechia | Music | #93 | | Top Free | Kazakhstan | Music | #249 | | Top Free | New Zealand | Music | #307 | | Top Free | Taiwan | Music | #355 | | Top Free | Russia | Music | #451 | | Top Free | China | Music | #453 | | Top Free | Denmark | Music | #460 | | Top Free | Austria | Music | #487 | ## Pianoscope Discovered Keywords -
