CF Stopwatch 作者: pratikrkcha

CF Stopwatch is a lightweight and distraction-free timer designed specifically for Codeforces users. It helps you track your problem-solving time with a clean interface that blends perfectly with the Codeforces UI.

🚀 Key Features

No-Panic Mode
When you open a problem, the timer waits for at least one minute before starting automatically. This gives you time to calmly read and understand the problem before the clock begins.

Manual Start Option
Prefer to start the timer yourself? You can start it anytime with a single click.

Auto Freeze on Accepted
As soon as your solution is accepted, the timer automatically freezes, preserving your exact solving time.

Persistent Timer
The timer continues running even if you switch tabs or navigate within Codeforces — no interruptions, no resets.

Native Codeforces Look & Feel
The UI is designed to match Codeforces perfectly, so it feels like a built-in feature rather than an add-on.
