About this app

Transform your photos with the iconic Atkinson dithering algorithm — the same technique used on the original Macintosh by Bill Atkinson. Create stunning retro-style images with a single tap. # What is Atkinson Dithering? Atkinson dithering was the algorithm behind the classic 1-bit graphics of early Macintosh computers. It converts photos i nto beautiful two-tone pixel patterns, producing images with a distinctive vintage charm and remarkably small file sizes. # Features - Real-time Atkinson dithering preview through your camera - 7 retro-tech color palettes: Terminal Green, Amber Monitor, Original Macintosh, Game Boy, Apple II Green, White Phospho r, and classic black & white - 5 iconic frames inspired by computing history: MacPaint, Classic Mac window, Terminal, White Frame, and frameless - Adjustable brightness control - Rounded corner option - Square photo output optimized for social media - Lightweight PNG output with tiny file sizes # Color Palettes Go beyond black and white. Choose from color palettes inspired by legendary displays — the green glow of VT100 terminals, the warm amber of IBM monitors, the creamy screen of the original Macintosh, and more. # Retro Frames Wrap your dithered photos in frames inspired by classic software. The MacPaint frame features pixel-perfect tool palettes and menu bars, just like Bill Atkinson's legendary paint program. The Classic Mac frame recreates the iconic window chrome of early Macintosh. # Perfect for - Retro and vintage photo enthusiasts - Pixel art lovers - Social media posts with a unique aesthetic - Anyone who appreciates the beauty of 1-bit graphics
