FAQ
Frequently asked questions
Is this an official Codeforces app?
No. Rating Widget for Codeforces is an independent, unofficial app made by an individual developer. It is not affiliated with or endorsed by Codeforces, and it only shows information that anyone can see through the public Codeforces API.
Do I need to sign in?
No. Just enter your Codeforces handle. The app never asks for a password or account access, and you can change or clear the handle in Settings at any time.
The contest ended but my rating hasn’t changed.
Codeforces usually takes a few hours to finalize results and update ratings. Once it does, the app and widgets follow, and right after a contest the widgets check every 30 minutes. You can also pull to refresh in the app or tap the refresh button on a widget.
How often do widgets refresh?
About every 3 hours, every 30 minutes after a contest, and 15 minutes after a failed attempt. The actual interval depends on iOS and Android battery policies.
Does it cost anything?
It’s free. The dashboard shows ads, and a one-time in-app purchase removes them all.
Is it available on Android?
The Android version supports rating, contest and friends Home Screen widgets and is getting ready for Google Play.
