This app is a gem
I was reading through a book about Riemann called Prime Obsession and wanted to graph alongside with the authors examples. Fortunately, I came came across this app. It is perfect, but what really blew me away was the simplicity and power of the app. Spend some time with included examples to see what Im talking about. I love stumbling across well designed apps like this one.
