Hello dear contestants,
I hope you guys are doing well. I have developed an App that is now currently on the Google play store. It's for the people who regularly participate in contests and unfortunately forget about upcoming contests and they missed or cannot join at a time! I faced this before. So! here is the key! 
This App "Codeforces reminder" will start ringing 60 seconds before the contest and there's no chance to miss. And Also,
You will be able to watch your previous
-submission list
-contest history
-rating
-max up rating
-max down rating
-best rank you achieved ever
-worst rank you achieved ever
-total number of contests you have participated
-upcoming contest's in queue
-finished contests and their rating changes
**most important thing you will be able to set a reminder for the upcoming contest and after that, you will be notified before that contest. So there is no chance to miss any contest!
**after logging in to your app UI color shadow will be changed according to your contest rating on codeforces. Have a nice day!
