Nice catch. Edited the title. Maybe not equally mind blowing, but still pretty inspiring to such that so many technicians rely on it and love it so fondly.

Especially the reviewer who mentioned him using an old version of the software running on a PocketPC until it got released on iOS.

Disclaimer: I don't tune/play the piano, just heard from a friend who had a technician at home that used some expensive software on their iPad tune it.
