Mission Brief

TodoUp is a modern task management and daily productivity mobile application published on the Google Play Store. Built with Flutter 3 and Dart, backed by Supabase PostgreSQL, and engineered with an offline-first Hive storage engine, TodoUp allows users to organize their daily schedule, receive smart AI task suggestions, and trigger scheduled local notifications seamlessly even without an internet connection.

Key Features

  • Task Organization: Create, categorize, prioritize, and manage complex daily tasks with custom tags
  • AI Smart Suggestions: Context-aware automated breakdown of broad goals into actionable subtasks
  • Scheduled Reminders: Background notifications powered by `flutter_local_notifications` with direct task deep-linking

Offline-First Sync Engine

  • Hive Local Storage: Instant zero-latency UI writes stored in local binary Hive boxes
  • Supabase Cloud Sync: Bidirectional conflict-free sync resolving updates via timestamp comparison
  • Supabase Authentication: Secure JWT-based email/password authentication persisting across app sessions
