This is another short experimental App. You can set parameters, how infectious, how dangerous a virus is, how long contagious and sick people are and you can set rate of no going out by slider every "day" new. I wrote B4J and B4A version. In Android you need good eyes to see the dots (people). Tab the graphic to change the settings, than tab again. I wanted to test the preference dialog, this was one reason to write this app.
