Voice In the Beginning

Instructions are not very clear on what the user is supposed to do to practice the techniques You get a short description of the tool but its almost too short with no real call to action You can play a prerecorded audio recording that I assume is a representation of what youre supposed to do with your own voice but what the audio recording sounds like is a sick person trying to do the scales with their voice with a piano in the background and sometimes the prerecorded voice doesnt complete the whole scales That and the user interface design is one of the worst Ive ever seen A major flaw in the experience is that you cannot go back to the list of toolssessions from a specific toolsession You have to hit the home button first then hit the practice button from the home screen In reality the practice button in the top left should take you from the specific session back to the list of sessions Right now that topleft practice button does nothing Poor functionality in my opinion I will update my review after I see improvements made        Instructions are not very clear and functionality flaws
