This app is a dud

Dont waste your time, money or precious storage on this app. Just like other reviewers said, it constantly prompts you to upgrade. The music is beautiful but I need more than that. Not scientifically accurate on a basic level as the light spectrum bar at the bottom is not correct. They put x-Rays before/left of visible light! (It should be infrared.) Im deleting this app after I write this review.
