6. Signature Design Concept

Interactive Growth Timeline
The homepage of the prime-pregnancy app will feature an interactive growth timeline that visually represents the baby’s development week by week.

• Design Details:

  • A scrollable 3D timeline where each week is represented by a glowing orb.
  • As users scroll, the orb grows larger, symbolizing the baby’s development.
  • Clicking on an orb will display detailed information about that week, including baby size comparisons (e.g., "Your baby is now the size of a peach!") and relevant tips.
  • Subtle animations, such as floating particles and gentle color transitions, will create a magical, immersive experience.

• Micro-interactions:

  • Haptic feedback for mobile users when interacting with the timeline.
  • Smooth transitions between weeks with soft sound effects (e.g., a heartbeat sound when reaching a new milestone).

This feature will make the app instantly captivating and provide users with a sense of connection to their baby’s growth.

7. Non-Functional Requirements

• The app must load within 3 seconds on a standard 4G connection.
• The system should support a minimum of 10,000 concurrent users.
• Data must be encrypted to ensure user privacy and comply with GDPR regulations.
• The app should be accessible to users with disabilities, adhering to WCAG 2.1 AA standards.

8. Tech Stack

• Frontend: React for Web, React Native for Mobile App

• Database: MySQL (using Alembic for migrations)
• AI Models: GPT 5.2 for user-friendly responses, Claude 4.5 Opas for academic or coding work
