Like i had said before pitch really has nothing to do with tuning, yes the sound may be different in pitch but you can use your 1st string to check your 6th string true? that's because they are of the same note. when an actual guitar tuner checks the amount of vibrations the string is generating it doesnt use sound, it uses electricity that is created by the vibrations of the air, your ear does the same basic thing. Use the general tuning that you do on your guitar then use this as a precise way to put/keep it in tune. and for the banjo and ukulele, learn basic tuning and use a reference guide, as you suggested, to find the correct notes, for each string, and tune. though the pictures are quite cool, and it is a good way for the people who dont know the notes of the strings, I am not saying get rid of it, but for those who know the tunings, set up a page that plays the note desired, and allows them to tune form there ( Note to Self: Somehow tell Microsoft to put a microphone on the ZuneHD.)

Oh and a question on the scales, chords. and other such things : Are you going to put in pentatonic, Natural, Minor, Major, #, b, and other scales in there? If so, a fairly good idea is to make a sprite the size of the screen on landscape view. the same basic idea works for the chords. If needed send me all your chords, scales, and such and ill make them into the correct sized sprites. PM me if you want me to do so.
