User reviews

CF Analytics is a highly praised Chrome extension for tracking competitive programming progress with a simple and effective interface. Users appreciate its ability to motivate and guide practice by showing problem ratings and progress. It reduces reliance on external tools and enhances usability. However, multiple users requested filters for problem ratings to manage large solved problem sets better, and a few noted a minor display bug with small problem counts. Overall, it is regarded as a valuable tool for Codeforces users.

Pros

Helps users track their problem-solving progress and practice effectively.
Simple, user-friendly, and well-presented interface.
Motivates users by showing problem ratings and other profiles for targeted practice.
Highly useful for competitive programming improvement.
Reduces the need to visit external resources like Codeforces Visualizer by integrating tracking features.

Cons

Lacks a filter for problem ratings, making it hard to sort problems after solving many low-rated ones.
Minor display bug when the number of solved problems is small, causing odd quantity representations.

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)
