Overview
Product summary
Review the store description, core capabilities, and common use cases.
CF Analytics Chrome extension improves the Codeforces profile webpage to include statistics of problems solved by the user. The ‘Problem Rating’ graph is a bar chart showing problems solved for each problem rating. The ‘Tags Solved’ graph is a doughnut chart displaying tags solved across any problem and also lists a count for each tag. The ‘Unsolved Problems’ shows a count of all problems attempted with not correct verdict and also lists them.
The extension communicates only with the Codeforces API and runs entirely on the browser.

please update
Best one!
great tool
Very useful! But it would be so much better if i could click on chart column and then see problems that has tags of this chart. Thanks!
Great stuff, helps you know what problem rating to target and get motivated by other profiles
Great extension, but please, also add filter for Problem Ratings, so I could check questions from 1200* >= (it became unreadable because I solved a lot of 800* questions)
Great To Track practice.
been using it for 4 months now ,and it's very useful and simple well done ,Dev.
Simple and to the point!
