Hello Codeforces community!↵
↵
How many times have you missed an upcoming **Codeforces Round (Div. 2 / Div. 3 / Educational)** or an **AtCoder Beginner Contest** simply because you forgot the start time or got confused with time zone conversions?↵
↵
As competitive programmers, we participate in contests across multiple platforms like Codeforces, AtCoder, CodeChef, and LeetCode. Managing alarms manually for every single contest can be annoying and easy to forget.↵
↵
To solve this, I built **Contest Alarm App** — a free, open-source, local-first Android app designed specifically for competitive programmers!↵

### Key Features↵
↵
- **Multi-Platform Auto-Sync**: Automatically fetches live contest schedules from Codeforces, AtCoder, CodeChef, LeetCode, Clist and more.↵
- **Division-Wise Auto-Alarms**: Set automatic alarms for your preferred divisions (Div 1, Div 2, Div 3, Div 4, Educational, ABC, ARC, Starters) as soon as new contests appear.↵
- **Auto-Reschedule on Time Changes**: If Codeforces delays or reschedules a contest, the background worker automatically updates the schedule and adjusts your alarm accordingly.↵
- **Reliable Lock-Screen Alarms**: Rings a loud alarm 30 minutes before the contest start time(alarm time can be customizable to 15 minutes, 1 hour or 2 hours before contest start), waking up your screen even if the phone is locked or in Doze mode.↵
- **Custom Alarms with Notes**: Set manual alarms with personal notes for virtual practice or study sessions.↵
- **Offline-First & Local Storage**: Uses Room SQLite Database. Your scheduled alarms continue to work seamlessly even without internet connectivity.↵
