OK, but needs improvement.

This is a good first effort, but it seems a few things werent thought through thoroughly:

• It needs an octave selector. I dont quite understand the choice to include only pitches *below* middle C. Every pitch pipe Ive ever owned started at middle C and included the octave above. That said, Im sure the lower octave is useful to some, so the best solution would be an octave selector -- right on the main page, not hidden under the info button.

• Its also ironic that the app displays a treble clef, although it plays notes from the bass clef. :-) Display a bass clef for the current pitches, and have the displayed clef change to treble, when the user chooses the upper octave (as proposed). Simply tapping the clef, itself, would be an ideal way to select octaves without cluttering the user interface with another button. :-) If youre concerned about tapping accuracy, you could make the clefs a bit larger, allowing them to descend into the center of the circle a bit. (Or better yet, just make the blank area immediately beneath the clefs "tappable," without enlarging the clefs, themselves.)

• Give us a "single-play"mode. Its tedious having to re-tap each pitch, to stop it from repeating. One tap should play the sample once, instead of over and over again. Again, this behavior could be specified via a preference. But it seems to me that the single-play mode would be most practical -- especially in live-performance situations.

• If youre going to include repeating pitches, have the samples properly looped. The current, start-and-stop pitches are cheesy. Loop them! We have the technology!

• Finally, remove the "Currently Playing" text. Its unnecessary, and its clutter. When a pitch name is tapped, a very clear circle is drawn around it. Nice! So, under what circumstances would someone tap a pitch, ignore the big circle, and look at the bottom of the screen in order to determine -- in small text -- whats currently playing? :-)

As I said -- a good first effort. Its almost there. Hopefully an update will hit the "sweet spot."
