EloMath turns math practice into a ranked progression system. Instead of only tracking streaks or completed exercises, EloMath gives learners a visible chess-style Elo rating that changes as they solve problems of different difficulty levels.

The goal is to make math progress easier to understand: users can find their current level, practice problems matched to their ability, and climb through increasingly challenging tiers. EloMath is designed for students, self-learners, and anyone who wants a more motivating way to train math skills.

Key features:

• Chess-style Elo rating for math practice
• Difficulty-based problem progression
• Ranked tiers to make improvement visible
• Practice across multiple math levels
• Website and app access
• Built for learners who want measurable progress

EloMath is especially useful for people who enjoy competitive learning, structured practice, and clear feedback on their mathematical growth.
