PitchLab became available on IOS and thus accessible to me just before the book’s proofs were due, which did not leave me enough time to do anything more than report that it was a powerful and versatile app particularly for string players. As you know, in the book, I highly recommended Cleartune and still do, however, when I recently received the warning from Apple that Cleartune might not be available after the next system update, I started to use PitchLab more and have grown to love it. PitchLab has so many modalities that makes it a versatile tuner; in fact, I think I can tune more accurately with it than with Cleartune. And, though I’ve never felt comfortable with strobe tuners before, PitchLab’s version is very easy to use. Finally, it shares one of the primary advantages that Cleartune offers—the ability to create your own temperament, which as you know is going to be more precise than the preloaded meantone temperaments that don’t tell you where the wolf is. What’s more, creating new temperaments in PitchLab is even easier than in Cleartune. Given that we may not have Cleartune around much longer, I think it behooves us all to become more familiar with PitchLab.
