If you sing - you NEED this APP!!

I sing barbershop, where pitch is paramount. This app gives you real time feedback, not only on hitting your note, but where you are within the range of the note! The only feature Id like is the ability to lock the screen to a single octave, and have the sung note show. The current implementation spans octaves, and the screen moves to show the note - or you can lock it, but its possible that the note youre singing is above or below the show range. Just show the note - I can figure out the octave!
