Cross-Platform Habit Tracker App

I need a habit-tracking application that runs smoothly on both iOS and Android. Core features include progress tracking with clear visual stats, configurable push reminders so users never miss a day, and a native share option that lets them broadcast milestones to their favorite social platforms.

The interface should feel professional and sleek: clean typography, subtle color accents, and smooth micro-interactions—no clutter or cartoonish elements. A cross-platform stack such as Flutter or React Native is fine, provided the final experience feels fully native and meets App Store and Play Store requirements.

Deliverables
• High-fidelity UI mock-ups reflecting the chosen style
• Source code and project files, logically organized and documented
• Tested release builds for iOS and Android, ready for submission
• A concise deployment guide for future updates

Acceptance criteria: progress charts update accurately as habits are logged, reminders trigger reliably even after a device reboot, and the share action opens the native share sheet with a pre-filled message.
