Sheer joy to use

I took up piano tuning with my local tuner 8 years ago and started the hard way; however excellent training. This app comes along and it optimises the tuning curve for you based on the inharmonicity readings. First he said my bass octaves were world class then he said the whole tuning of a Yamaha concert grand he’d restrung was amazing. Highly accurate, it is a joy to use. You can easily save files. Today I could microtune from 0.7c over, to 0.4c, my preferred area of 0-0.6c over. There is no tuner on earth who could differentiate between 0.3c over or under. This one does everything. Thoroughly professional it is a game-changer.

Perfect app

Perfect App for Piano Tunings. Also great support. I am using this app for years now and my tunings are much better than before.

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.

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.

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.
