The app peforms as promised and does a decent job. The User Inteface is very utilitarian and unispired though. I can't read kanji and no very little Japanese, so I can't comment on the app's accuracy. What I dislike most about this product was the lack of support from the author or Tabletop Adventures - see my comments on the product's front page and a solution to what I was inquiring about. The author doesn't provide any info in the Readme.txt file for running this app on anything other than a PC, which IMO is unnacceptable considering it's uses Java based scripting - noted for its universality. As it turns out, I was able to get it up and running on a Android Table with only a little reasearch. I don't understand why the author couldn't have made the effort and listed instructions similat to what I detailed in my front page comments. IMO, the same should be included in the readme file for procedures on using it on tablets running the Apple iOS operating system.
