Fluffier

Develop a cross-platform mobile application compatible with both iOS and Android operating systems, designed to deliver a smooth, intuitive user experience for end users. The core functional modules of the app include a user authentication system supporting phone number verification, third-party social login and secure password reset, a personalized content feed that dynamically displays targeted content based on user behavior preferences and browsing history, an interactive operation module allowing users to like, comment, bookmark and share content with one tap, a personalized center for users to edit profiles, manage published content, view account statistics and adjust system settings, and a lightweight notification center that pushes real-time updates for interactive feedback, system announcements and content updates. Prioritize interface simplicity and clarity in design, adopt a modern flat design style with consistent visual specifications for all buttons, text and interactive elements, ensure the app loads within 2 seconds on mainstream mobile devices, support offline caching of commonly accessed content to reduce data usage, and conduct full compatibility testing for devices with different screen sizes and system versions to eliminate lag, crashes or display anomalies. The app should reserve 20% of functional expansion space for subsequent iteration updates, support background silent update of core modules without forced user updates, and integrate a lightweight user feedback entry to collect user optimization suggestions in real time. The entire development process needs to strictly follow the specified timeline, complete functional testing and compatibility debugging before launch, and ensure stable operation under high concurrent access to meet the daily use needs of tens of thousands of active users.
