## What is CFClimb?

CFClimb is a companion for competitive programmers on Codeforces. It follows your week: get reminded before a round, compete, see your rating change, then upsolve what you missed.

Unofficial: CFClimb is not affiliated with or endorsed by Codeforces. It uses the public Codeforces API.

NEVER MISS A ROUND
• Upcoming, running and past contests, with live rounds pinned to the top
• A countdown to the next round, also on your Home Screen with the widget
• Reminders 1 day, 1 hour or 10 minutes before the rounds you pick. If Codeforces moves a round, the reminder moves with it
• Add upcoming contests to your calendar

KNOW WHERE YOU STAND
• Save your handle to see your rating, your tier and how many points you need for the next one
• Your solve streak, problems solved in the last 7 days and rated rounds at a glance
• A notification when your new rating is published, checked in the background

UPSOLVE WHAT YOU MISSED
• A queue built from your rated rounds: problems you tried but didn't solve, then problems you never opened
• Sorted from easiest to hardest, with difficulty and tags, and filters for tried or not opened
• Open any problem on Codeforces in one tap

PROFILES AND COMPARE
• Rating history, solved problems by difficulty and tag, verdicts, languages and an activity heatmap for any handle
• Compare two handles side by side
• Search contests by name or type

WORKS OFFLINE
• Contests and profiles you've opened are saved on your iPhone and load without a connection
• Light, dark or system appearance

No account and no sign-in: just your public Codeforces handle.
