Deep Green

A no-nonsense classical chess app.

- CLEAN UI: Deep Green offers a distraction-free experience in a clean, native user interface, with Liquid Glass on iOS 26 and later.
- CUSTOM PIECE DESIGN: Beautiful chess set designed specifically for Deep Green and rendered at high resolution in both outline and 3D throughout the app.
- MADE FOR IPAD: Dedicated menu bar, multiple windows, and refined trackpad, mouse, and Apple Pencil support. Squares highlight as you hover over the board.
- MADE FOR IPHONE DUO: Adapts to both displays and every pose. The board centers on the fold like a folding chess board, and the game controls follow the system into the vertical bar.
- TIGHT SYSTEM INTEGRATION: System-level sharing, drag and drop, AirDrop, undo/redo, contextual menus, Quick Look previews of chess files, Dark Mode, high contrast support and more.
- OPEN GAME FORMAT: Games can be shared, saved, copied, pasted, imported, exported in the ubiquitous, open source PGN and FEN formats. Deep Green can open chess files straight from the Files app.
- UNIQUE CHESS ENGINE: Enjoyable opponent with adjustable strength, praised for its humane gameplay, developed for Deep Green on the Apple Newton more than 25 years ago.
- TWEAKABLE APPEARANCE: Engage the knights in the game by having them turn towards the center of the board, apply a humane, slightly random placement of the pieces.
- IN YOUR LANGUAGE: Available in English, German, and Danish.
- MODERN ARCHITECTURE: Written in Swift as a fully native app – modern, maintainable, and prepared for the future.
- PRIVATE, AD-FREE: No ads, no tracking, no analytics, no nonsense.
