Atmo Engine

Replicate the dynamic 'Atmosphere' unlock transition effect from Nothing OS.
Bring the distinctive "Atmosphere" transition effect to your device.

Atmo Engine is an open-source live wallpaper engine designed to replicate the dynamic transition found in Nothing OS. When you unlock your device, your wallpaper smoothly shifts from a moody, blurred abstract view to a sharp, clear home screen.

Features:
• Original Atmosphere: Drifting ambient clouds that transition to a sharp view on unlock.
• Reverse Atmosphere: A deep, moody alternative that fades from clear to atmospheric clouds.
• Simple Frosted: A clean, uniform frosted glass effect for a minimal look.
• Playlist Mode: Select multiple wallpapers and have them rotate automatically.
• Customization: Fine-tune the experience with sliders for blur strength, grain/noise texture, and zoom levels.

Privacy & Performance:
• Completely Open Source (MIT License).
• No Internet Permission required.
• Efficient battery usage using OpenGL.
