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.
If you like Deep Green, please rate it favorably on the App Store.
The main reason I bought this game was the gorgeous design, and the new design just look like a generic life-less chess app :(The old icon is also 10x nicer than the new one…Is there any chance of making the old green-classic them & app icon be an option? I am currently holding back from updating the app 😬😬Thank you!!
Prone to CRASHES

For years I have enjoyed playing chess using Deep Green but over that time it has become prone to crash. Often it will crash in the midst of a game but it can be restarted and resumes back where it was. But there are time when it crashes in the midst of an intense contest and restarting the application avails nothing; the board will flash back and immediately crash again. Fortunately, I have actually been able to capture the fatal board setups with a very quick screen shot to later continue on a more competent platform. I would consider this a fatal flaw for Deep Green especially considering that the last time this app was updated was at least 7 years ago at the time of this review; obsolete. Ostensibly the developers have become complacent.
Major UI Change READ BEFORE UPDATING
Jcalchi
This chess app is top notch—always has been. No other app is as enjoyable to use. BUT! This new update is a major change to the wooden board and pieces. It is no longer the green felt and classic wood. Look at the new version previews and make sure you’re ok with that before you update. The classic wood board is not an option. I wish it was. Also, the Steampunk engine’s gears no longer make noise. I miss both that and the old wood board.
Latest update ruined this game.

I used to love and play this chess app every single day. But, the latest update, 2/26, took away the ability to take back or replay moves, which completely takes away the game’s use as a learning tool. You can no longer back up and try different moves and outcomes. Features have been stripped away slowly for years, but this is the last straw for me. I’m now looking for another chess app. Very sad. :(
Deep Green 2.1.2 is made for iPhone Duo and gives the board more room everywhere.
- MADE FOR IPHONE DUO: Deep Green adapts to both displays and every pose. The board keeps to the upper half in laptop pose, centers on the fold in book pose – like a folding chess board – and spans the fold when open flat. The game controls follow the system into the vertical bar.
- ROOM FOR THE BOARD: The board takes all the space the bars leave it and stays centered on the screen – hide the bars, and it fills the screen. On iPad, the game controls move to a bottom toolbar in portrait, centered within reach of either thumb, instead of crowding the title.
- POLISH: The Suggest Move symbol always completes a full turn, and Game List boards no longer animate into place while you scroll.
Plus all the improvements in versions 2.1 and 2.1.1, listed below.
Deep Green 2.1 is the biggest update in years: a refreshed design, chess files, board images, and a first-class chess board on iPad – and now iPhone Duo.
- REFRESHED DESIGN: Liquid Glass and a new app icon on iOS 26 – refractive on iOS 27 – improved chess piece design in the Game List, and a modernized welcome sheet.
- MADE FOR IPAD: Dedicated menu bar, multiple windows, and refined trackpad, mouse, and Apple Pencil support. Squares highlight as you hover, and tints show where a dragged piece may legally land.
- CHESS FILES: Import PGN and FEN files from the Files app, by drag and drop, or via AirDrop – with Quick Look previews and thumbnails showing the actual position.
- BOARD IMAGES: Copying or sharing a game or position includes an image of the board. Save it straight to Photos: it follows the orientation the board is shown with, is named after the game, and carries players, event, date, searchable keywords, and the complete game with it.
- SMARTER PLAY: Pick between variations with the Step Forward button, choose the engine's search depth for Suggest Move, press and hold Undo to redo a move, take back the move that ended a game, and stalemate correctly ends the game in a draw.
- IN YOUR LANGUAGE: German, UK English, and Danish localizations.
Plus a zoom transition into games, tips introducing features, smoother piece dragging on ProMotion displays, and a long list of fixes. See the full change log via What's New in the app.
