Basic but it works
I am really enjoying this app. I love how this lets shows me what is correlated and one cannot find causation without knowing correlation first. Unfortunately it looks like the developer isn’t around anymore (dead website) because there are a few things this app desperately needs (like contact info for comments/questions, a FAQ page, and especially instructions! I have no idea what the circles/half circles mean on the correlation page and I had no clue I could click something more than once and it would show the number on the correlation page. At the same time, it’s still usable so I will continue.
