Build

cd app/
./gradlew assembleDebug    # Build debug APK
./gradlew installDebug     # Install on connected device/emulator
./gradlew assembleRelease  # Build release APK (minified + shrunk)

Prerequisites

• Android Studio Hedgehog or later
• JDK 17
• Firebase project with Auth, Firestore, Cloud Messaging, and App Check configured
• google-services.json in app/ directory
• RevenueCat project configured for Google Play

Design Principles

• Warm & Intimate — The app should feel like a private emotional space, not a productivity tool
• Privacy-first — Data isolated by couple, strict Firestore rules
• Offline-resilient — Room cache keeps the app fast without network
• Intentional — Short, meaningful interactions. 5 good minutes > endless scrolling
• 2026 modern — Smooth Material 3 animations, instant feedback, no jank
