For almost a week already, Codeforces WatchR offers to its users brand-new feature called "Problems".

This is the last (but not the least) of tabs, which allows anybody to:

  • browse all Codeforces problems without any limits
  • search problems you are interested in by its name or contest id, where it appeared for the first time
  • mark chosen problems as "Favourite" to upsolve it later or just share with friends
  • view any problem's condition, of course

Hindi translation

Thanks to NiKS001 and HackedAlways, Codeforces WatchR is now translated to Hindi (even though it's not so popular as I initially assumed). Here is the PR.

Google Play Statistics

My latest post has made its way to the Top, which gave us unprecedented attention from Codeforces community. We truly appreciate all feedback we got and looking forward to make Codeforces WatchR even better in future.

To sum up "the hype" of the last month, here are some stats:

  • 1K+ new users acquired (from which 300+ lost)
  • 900+ active users at this moment
  • 50+ new notes with 4.7+ average
  • 24 stars on GitHub
  • just 8 crashes (all fixed in latest version)

Further development

Of course, we won't stop on what's implemented right now. Just to give you idea on what's coming, here is the list of issues on GitHub.

Traditionally, thanks to BOGDAN_ for development efforts and ideas!

Also, in the last feature we used KMP algorithm for quick searching among of 5000+ problems. It gave us tangible results! :)

In the contests section , when we want to add the reminder for the contest the app directs to google chrome calender. Can you please shift it to google calender app available in phones? It will be very helpful.

Please consider implementing an option to show problem difficulty without tags in problems tab.

    Glad to see you've found a value in Codeforces WatchR ;)

    I would be happy to also get a feedback on other features from you: what's good, what's can be improved, what's useful, what's useless and what's missing.

There were few minor problems in version 1.4.0, which are now fixed in version 1.4.2. So don't hesitate to update your Codeforces WatchR, it's already available in Google Play.
