I've created a mobile-first TikTok clone app with the following features:

Key Features:

• Mobile-optimized design - Designed specifically for mobile devices with responsive layout
• Vertical video feed - Full-screen vertical videos like TikTok

• Interactive elements:

  • Play/pause video controls
  • Like, comment, share, and bookmark buttons
  • User avatars with follow buttons
  • Music attribution

Design Elements:

• Dark theme - Black background with white text for the authentic TikTok look
• Bottom navigation - Home, Discover, Create (+), Inbox, and Profile tabs
• Top header - "Following" and "For You" feed options
• Right sidebar - User actions and engagement metrics
• Gradient overlays - For better text readability over videos

Mobile-First Features:

• Touch-friendly buttons - Large tap targets for mobile interaction
• Responsive layout - Optimized for mobile screen sizes
• Smooth scrolling - Vertical feed with smooth scroll behavior
• Video controls - Tap to play/pause functionality

The app includes mock video data with realistic engagement numbers, user profiles, and video descriptions in both English and supports the Vietnamese context you mentioned. The interface closely mimics TikTok's familiar user experience while being fully responsive for mobile devices.
