TuneLab Piano Tuner

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.

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!

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
