Kid-friendly Spanish flashcards with:

• email/password auth
• user-owned cards with optional images
• English->Spanish and Spanish->English multiple-choice quizzes
• adaptive question weighting (weaker cards appear more)
• per-user progress dashboard
• Google Translate suggestions for card creation

Setup

1. Install gems:
   • bundle install
2. Create and migrate DB:
   • bin/rails db:prepare
3. (Optional) Configure Google Translate credentials:
   • set GOOGLE_CLOUD_PROJECT
   • set GOOGLE_APPLICATION_CREDENTIALS to your service account JSON path
4. Start server:
   • bin/rails server
5. Visit:
   • http://localhost:3000

If Google credentials are missing, card creation still works; translation suggestion simply falls back silently.

Test

• bin/rails test
