I recently came across ContestBell, a simple tool made specifically for competitive programmers.

It tracks upcoming contests from platforms like Codeforces, LeetCode, CodeChef and AtCoder and sends you notifications so you don't have to keep checking every platform.

It also recently added Google Calendar integration — connect your calendar once and your upcoming contests can be added automatically, with the correct time, duration and contest link.

If you regularly miss contests because you forget about them or get confused with timings, give it a try:

It's free, and honestly, it's a pretty neat little tool for anyone who participates in contests regularly.

Happy coding!
