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
App crashes every time I try to take a picture. Really unfortunate—looks like it would be cool.Settings are inaccessible. Badly in need of an update.UPDATE: I am now able to both take a picture without crashing, and access the settings! (Settings are still a bit difficult as it’s buttons of white text on a slightly off-white background.) I’m glad to see an update, thanks.

Dude what happened
narutofan778
Was an amazing app and whatever happened in the last few updates totally ruined it? For such a small app I never expected this to randomly occur. Not only did you add ads but the app is also simply unusable outright (won’t work at all now). If you offer a paid version without ads for like $1.99 I’d pay for it and recommend it to people but please don’t ruin this cool lil thing.
