WordWalk (React Native) — GRE Memorization + To‑Do + Streak Rewards

This is an Expo React Native starter you can drop into a fresh project.

What you get (MVP)

• Daily review with a simple spaced repetition (SM‑2) schedule
• Daily goal → streak (streak increases only when you hit the goal)
• Coins + XP per review
• Badges (streak + total review milestones)
• To‑do list (today view + all view)
• Dark/Light mode with a setting override (system / light / dark)

The word list is seeded from src/data/words.json (copied from your existing dataset).

---

1) Create a new Expo app

npx create-expo-app WordWalk --template
cd WordWalk

Pick the TypeScript blank template if the CLI asks.

2) Install dependencies

Use expo install when possible so versions match your SDK:

npx expo install @react-navigation/native @react-navigation/bottom-tabs @react-navigation/native-stack
npx expo install react-native-screens react-native-safe-area-context react-native-gesture-handler
npx expo install @react-native-async-storage/async-storage
npm i zustand

3) Copy the code from this folder

Copy these into your Expo project root:

• App.tsx
• src/ (entire folder)

Your final structure should look like:

WordWalk/
  App.tsx
  src/
    components/
    data/words.json
    navigation/
    screens/
    store/
    theme/
    utils/

4) Run

npm run start

Then open on Android/iOS (Expo Go or a dev build).

Customization knobs

• Daily goal: Settings → Daily goal
• Theme: Settings → Theme
• Add your own words: replace src/data/words.json with your file (same structure).

---

Next upgrades (if you want to make it “journal publishable” level)

• Notifications (daily reminder + “due words” alerts)
• Analytics (retention, time spent, weakest sets)
• Search + favorites across all sets
• “Leech” detection (words you fail repeatedly) + targeted drills
• Cloud sync (Firebase/Supabase)
