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.

CodeHerald provides a new way to keep track of your code review queue, grouped by your next action needed.

When would you use CodeHerald?

• You work in a team that does code reviews.
• Your team receives ad-hoc code review requests via multiple channels: DMs, emails, bookmarks of filtered lists.
• Your team sometimes loses track of small pull requests, delaying them days.
• Your team find ad-hoc code review requests distracting, but cannot put a finger on why.
• Your team tried different strategies to improve code review process, and none of them felt right.

If any of the above is true, CodeHerald will help you.

What can CodeHerald do for you?

CodeHerald groups pull requests by next action: must review, needs an update, can be merged. It allows you to replace slack, emails, filters, and browser bookmarks with one single page that you can open at a glance and decide which PR to tackle next.
