Brilliant!

This is a well thought out AR app thats very much worth your money if you enjoy watching or learning vocaloid dances. Definitely a bit of a mind blowing experience to watch a life-sized vocaloid dance all your favorite choreography from any angle in your bedroom. The layout is minimalist and clean, the controls are intuitive, and nearly any function that you think should be available for an AR vocaloid app is there. Timing seems like itd be hard to perfect, but this syncs very well for the entire 4-5 minutes of each song. You can play it simultaneously with videos of cover dancers!

The developers were very through with details. It crashes perhaps once per 30-60 minutes of play, so its not really an issue. Out of the 20+ dances and models I loaded, only one model failed to work.
