vee VAH! app for iPhone and iPad

It’s an electronic accompanist for vocal warm-ups. Whether you are a singer who wants to start with the middle voice and proceed to placement, or you are a choir director tasked with easing many voices (and bodies!) from tension to readiness, the app operates the same:
o press Play to warmup to the exercises you selected last time, or
o scroll through the exercises,
o tap the ones you want,
o press the exercises "definition" button, and then
o press Play.
veeVAH starts with the easier exercises and proceeds to the more difficult ones.
To allow for breath support, it always inserts an 8-beat countdown between each exercise.
