I'll help you build VidShare - a mobile video sharing app based on this wireframe! Let me generate design inspiration first to create a visually compelling app, then build it.

Now I have the design inspiration and project structure. I'll create a modern, dark-themed mobile video sharing app with all the screens from the wireframe. Let me build this step by step.

I've built the complete VidShare mobile video sharing app based on your wireframe. The app features a dark theme with a teal accent color and includes all 8 screens:

1. Home (/) - Video feed with search bar, category filters, and recommended videos
2. Category (/category/[id]) - Filtered video list by category
3. Search (/search) - Real-time search with instant filtering
4. Upload (/upload) - Video file upload form with title, description, and category selection
5. Brag Board (/brag) - Community posts with likes and comments, plus a floating "write" button
6. Post Detail (/brag/[id]) - Individual post view with comments and like functionality
7. My Page (/mypage) - User profile with avatar, nickname editing, tier card, and uploaded videos
8. Tier System (/mypage/tier) - Progress tracking with Bronze/Silver/Gold/Platinum tiers and scoring rules

The app has a consistent bottom navigation bar across all screens and uses a modern, mobile-first design with proper Korean localization throughout.
