Hi there, Your goal is to develop a productivity tool for Android with task management, calendar integration, reminders, and offline functionality. My approach is to design a clean, intuitive UI optimized for productivity workflows, implement robust task creation and organization features, integrate with native and third-party calendars for seamless scheduling, and enable reminders for timely alerts. I’ll also build offline-first functionality with smooth data synchronization once the device reconnects to the internet, ensuring reliability anywhere. To better align with your vision, I have two quick questions: For calendar integration, do you want to sync with Google Calendar only or include other services like Outlook and Apple Calendar? Should offline synchronization be automatic in the background or triggered manually by the user for more control? I look forward to collaborating with you. Best regards,
