- plan a practice schedule for AtCoder contests
- see which problems my friends solved

## When to choose
- you want a progress tracker and problem search for AtCoder
- you need AtCoder problem/submission data via an API or dataset
- you want to analyze your competitive programming practice habits

## When to avoid
- you need support for other judges like Codeforces or LeetCode
- you want an offline desktop tool
- you need automated problem solving or contest bots
