Rating calculation was done using the formulae in this [blog](https://mirror.codeforces.com/blog/entry/20762) by Mike Mirzayanov. Compared to Cfviz, you might get different results for [Educational Rounds](https://mirror.codeforces.com/blog/entry/21496). This is because these contests are only rated for Div. 2 participants, Div. 1 participants count as official participants. Cfviz, as far as I am aware, does not filter out these contestants. In practice I have found the results to be closer to the actual Codeforces deltas.↵

Here is a preview of the app. Hopefully, this is useful to someone else. If you have any ideas of any more features to add, please comment. ↵
