PROGNOS turns your Codeforces history into a living dashboard — streak tracking, tag analytics, and classroom leaderboards for CP teams.
Aggregated from your Codeforces history automatically — no manual input, no spreadsheets.
52 weeks of practice, visualized. See every day you solved a problem and protect your streak.
Your full Codeforces rating history, charted. See exactly when you improved and which contests moved the needle.
Know which problem tags are holding back your rating before they cost you a contest placement.
Seeing a peer's daily streak and tag coverage motivates consistent practice far more than a personal dashboard alone.
Create a classroom in 30 seconds. Students join by CF handle. Rankings update automatically after every sync.
See who is active, who is falling behind, and which tags the whole team needs to drill — in one teacher dashboard.
Contest alarms, quick-view dashboard, and offline access — practice tracking that lives in your pocket, everywhere you compete. Download the Android beta now — on iPhone, install the web app straight from Safari: Share → Add to Home Screen.
A beta build — you may need to allow installs from your browser in Android settings.
