Poorly designed
This app is probably the best in the iPhone store but way too much time was spent on graphics instead of making a great, functional app. If youre looking to improve your pitch, their way of measuring it is clunky and not very helpful. This is virtually the only part of the app that can actually give you "feedback" on how youre doing and the needle measuring is small and moves counter intuitively to how your voice moves through the ranges. The skeuomorphic design really killed this app.
Still, download it, its the best of the worst!
