Downgraded rating

4/11/16: I can see by other reviews that Im not alone in my exasperation. (Read the reviews, app developer.) Not only can I not figure out how to hear my music within the app (other reviews show my same experience; music plays, but buried.) but when I go to the developed website to ask questions, get answers, or send an email... NO CONTACT WHATSOEVER. Im deleting this app and downloading Interval HIT by Deltaworks. Their description sounds like what Im looking for.
4/4/16: so far its exactly what Ive been looking for!
