Hi everyone,

I made a small Android app called ContestDeck for keeping track of programming contests. It shows running and upcoming contests from Codeforces, CodeChef, AtCoder, LeetCode, and a few other platforms in one place.

You can save contests, set reminders, add them to your calendar, and keep an upsolving list for finished Codeforces rounds. There’s also an option to follow Codeforces handles and see their recent progress.

I mainly built it for myself because I kept forgetting contests and losing track of rounds I wanted to revisit. I thought it might be useful to some people here too.

If you try it and notice anything broken, let me know.
