A private scorekeeping and Elo ranking app for friendly challenges across any sport.
Challenge Board is the project page for Haasta, a small private scorekeeping and ranking app for friendly challenges. Groups can log results across different sports and have opponents confirm each result.
Every group has one shared Elo leaderboard. Tennis, bench press, javelin, arm wrestling, and custom challenges all feed the same ranking, with a simple flow for groups, standings, new results, and history.
