6. Signature Design Concept

Concept: Interactive Progress Garden

The giant-cerate homepage will feature an Interactive Progress Garden. Users will see a virtual garden where each logged meal grows a plant. Healthier meals will result in vibrant flowers, while high-calorie meals will grow duller plants.

Details:

• Animations: Plants grow in real-time as users log meals. Swapping a high-calorie item for a healthier option will instantly brighten the plant.
• Transitions: Smooth transitions between sections, with the garden subtly shifting colors based on the user’s progress (e.g., greener hues for better calorie management).
• Micro-interactions: Tapping on a plant reveals detailed stats about the meal that contributed to its growth.
• Mood: A playful yet motivational environment that encourages users to "cultivate" their health.

This unique design will make the app visually engaging and emotionally rewarding, ensuring users feel connected to their progress.

7. Non-Functional Requirements

• The app must load within 2 seconds on Android devices.
• The system should support at least 10,000 concurrent users.
• Notifications must be delivered in real-time.
• Data storage must comply with GDPR and Indian data protection laws.
• The app must be compatible with Android versions 10 and above.
