I've been using this app for a long time, but from the last 2 month the app Isn’t even opening the interface after giving cf handle. I've tried to login several time, using different ip, different cf handle and different devices but every time It's only get loading. Please update the app Update: Thanks for fixing all bugs and for the new UI. Great app but rating curve was more beautiful before. Thanks

The Sumbit section is great. It has syntax highlighting and auto ident - Feels just like code forces but on mobile. However, there are two problems: 1. When writing the text on mobile, the text does not fully appear - it scrolls in a text box until the next space. 2. Ads are okay but are irritating when they appear during writing code in the sumbit tab. This can disrupt the trail of thought whilst writing code for a solution. Would appreciate ads not appearing whilst writing code.

Overall the UI is intuitive and good enough for a competitive programmer. The login system should be checked so that user password verification can be done during logging in. Also, a search user field should be provided. The stats provided are helpful. Edit: The app crashes on opening contests questions. A zoom-in feature in visualizer graph would be helpful.

Thank you for you feedback. The login is not password verified for the reason being you can directly search any user by providing their username and access their information. But I will surely try and incorporate your suggestions in the upcoming versions.

What’s new

The app now has a code editor where you can write code of a problem in C++, Java and Python language. And you can directly submit the code on Codeforces.
