Slash Cards turns the Claude Code slash command catalog into a focused, beautiful study app. Quiz yourself two ways: see a command and pick the right description, or read a description and pick the right /command. Built for developers who live in Claude Code and want to actually remember what /compact, /resume, /security-review, /hooks, and the rest of the catalog do. WHAT'S INSIDE • 40+ documented slash commands, kept current as new Claude Code releases ship • Command → Description quiz mode • Description → Command quiz mode • Mixed mode that alternates both directions • Category filters: built-in, plugin, hooks, MCP, and more • A polished Library to browse the full catalog with search • Per-command detail pages with examples, versions, aliases, and notes • Mastery tracking: answer a command correctly five times to lock it in • Stats: streaks, daily activity, accuracy, and a per-category breakdown WIDGETS • Card of the Day on your Home Screen (small + medium) • Lock Screen accessory with today's command • Control Center button to jump straight into a quiz round 18 LANGUAGES Slash Cards is fully localized, and you can pick your language in Settings independently of your device language. DESIGN • Anthropic-inspired warm coral palette • First-class Light and Dark Mode • Built natively in SwiftUI MEMBERSHIP One simple membership unlocks everything: unlimited practice, every study mode, the full searchable Library, Home Screen and Lock Screen widgets, daily streak reminders, and mastery tracking.
