Penote

A lightweight, offline-first note-taking app for React Native (Expo) with PDF export.

✅ Overview

Penote is a modern mobile note app with:

• local persistence via @react-native-async-storage/async-storage
• search (title/body)
• pin/favorites support
• create and edit notes
• export note as PDF (expo-print + expo-sharing)
• onboarding on first launch
• dark/light theme based on system color scheme

📁 Repository structure

• App.js — navigation and onboarding logic
• screens/HomeScreen.js — notes list, search, pin, delete, export, create
• screens/EditScreen.js — create/edit note form
• screens/FavoritesScreen.js — pinned notes view
• screens/OnboardingScreen.js — initial setup prompt
• theme.js — light/dark color palette
