The Concept
In the crowded market of personalization apps, quality and speed are the differentiators. Cool Walls was designed to be more than just a gallery; it is a dynamic content delivery platform. The goal was to create an immersive experience where users can discover high-definition and live wallpapers with zero latency, while giving the administrators full control to update trends daily without releasing app updates.
The Solution
Rehmall Agency delivered a dual-platform solution (Android & iOS) using Flutter, backed by the real-time capabilities of Supabase. We engineered a sophisticated backend architecture where a dedicated Web Admin Panel acts as the command center. This allows the admin to upload, edit, and delete wallpapers instantly, pushing new content to thousands of devices in real-time.
Key Features
Immersive Media Experience: Support for high-resolution static and Live Wallpapers that bring home screens to life.
Offline Access: A smart downloading system allows users to save their favorite art and access it anytime, even without an internet connection.
Auto Wallpaper Changer: A background service that automatically refreshes the user's wallpaper at set intervals, keeping the device looking fresh.
Personalized Collections: Users can categorize content and create their own "Favorites" list for quick access.
Adaptive UI: A stunning user interface that automatically adapts to Light and Dark modes, ensuring visual comfort in any environment.
Smart Notifications: Integrated push notification system to alert users about new collections, trending wallpapers, or app version updates.
The Management Hub (Admin Panel)
Behind the beautiful app lies a powerful web dashboard built for total control:
Content Management: Upload, delete, and categorize wallpapers instantly.
Analytics: Track popular categories and download metrics.
Version Control: Manage app updates and notify users directly from the web.
The Tech Stack
To ensure high performance and media handling:
Mobile Framework: Flutter (Dart) for smooth, 60fps animations.
Backend & Storage: Supabase (for scalable database and media storage).
Admin Panel: Flutter Web.
State Management: Provider / GetX.
The Result
Cool Walls represents the perfect blend of aesthetic design and robust engineering. By decoupling the content from the app build, Rehmall Agency created a scalable product that stays relevant daily, offering users a premium customization experience that is fast, beautiful, and reliable.
