A solo maker uses Claude Code to test a pickup volleyball app

In Singapore pickup volleyball, organizing a game can be harder than playing it. A game needs about 12 people, but last-minute dropouts are common, so organizers end up asking across several group chats to fill empty spots. Even when enough people arrive, large skill gaps can make the game one-sided and less fun.

Coterie is an early app built to reduce that . An organizer can post the date, court, open spots, and skill level, while players can browse and filter games by location, skill level, and schedule. The app is being built solo with Claude Code, Anthropic’s , to move faster without a team.

The main question is not design polish yet, but whether this pain is strong enough that people would actually download an app for it.
