This is the best app for generating Conway's Game of Life. However, it needs an option for the universe to not wrap around, as well as a way to change the rules, for High Life and whatnot. And, the best possible improvement you can make would be the ability to not place cells immediately, but to touch your finger, have the pattern appear, but then be able to move the pattern by dragging your finger. That would avoid any irritating accuracy failures. All in all, awesome app.
