MainLine: Chess Trainer

MainLine is a chess trainer built to improve pattern recognition. It uses spaced repetition to help you remember tactics, endgames, and ideas from your own games, so study turns into usable over-the-board recall.

Train smarter with MainLine:
- Game-based drills built from your Chess.com and Lichess history
- Spaced repetition that resurfaces patterns before you forget them
- Interactive practice for tactics, endgames, puzzle themes, and key lines
- Quick daily sessions, streak reminders, and progress tracking
- Daily puzzles to challenge yourself

Instead of passively reviewing positions, MainLine helps you actively remember them. Review mistakes, revisit patterns, and build stronger chess instincts one session at a time.

Install MainLine and make your study stick.
