Really cool – Math Ninja AR Review

This is a neat math app, just got it yesterday. I don’t see any settings for difficulty and there didn’t seem to be instructions either. Which you don’t need if you put the map on a low enough surface if you don’t you can’t see the problems at the top of the board. I updated today and now have a ghost icon of the app along with the real app icon could you please fix it because it will not let me delete the ghost icon either. Thank you!
