So-So
I DO have the latest version :)
I find this app crashes a LOT. It also misidentifies notes too. A D on my oboe is always shown as F#. My tuning may not be perfect, but it is not that out. Although perhaps better than nothing (it does help ensure the tuning notes A and Bb are in tune), its probably not worth the money. Its of no use to me when I try to check that my upper register is not sharp!
