Blur Photo Editor App Development

Problem Statement A lot of users want to blur backgrounds, hide sensitive details, or create portrait-style depth effects but most desktop tools are too complex. Goal: Create a powerful yet beginner-friendly blur editor that works beautifully on mobile.

Objectives - Provide precise background and object blur, adjustable by users - Offer easy controls so even beginners can edit photos fast - Support sharing to social platforms - Deliver a smooth, responsive UI on iPhone/iPad

Depth & Blur Tool: users can blur background regions with adjustable intensity and zoom focus, simulating depth-of-field effects like a professional camera.

Selective Blur Brush: brush over areas to blur specific parts (background, objects, etc.) with precision.

Photo Frames & Effects: stylish frames and editing effects to enhance aesthetics around the blurred image.

Export & Share: direct sharing to Instagram, TikTok, and other social platforms to showcase edited photos.

iOS Platform: Swift & SwiftUI for native performance

Image Processing: Core Image & Metal for real-time blur rendering

UI Design: Custom touch controls (brush, sliders) for blur intensity

Storage & Sharing: iOS Photos integration + share sheet support

Simple workflows: One-tap blur + intuitive brush tools

Interactive sliders: Users adjust blur strength/precision without confusion

Preview before export: Real-time previews before saving

Outcome A user-friendly mobile editor that helps anyone turn ordinary photos into professional-style portraits or privacy-protected images without steep learning curves.

Smooth performance even with high-resolution photos due to optimized Core Image pipelines.

Balancing performance & quality: Used Metal shaders for blur to keep UI responsive.

Precise masking: Developed custom brush logic to ensure accurate blur regions tailored by user touch.
