Bitfold: Retro Game Emulator
Foldable handheld + free games
Free · Designed for iPad. Not verified for macOS.
Your pocket console, unfolded. Fold your iPhone Duo like a laptop: the game on top, the hinge on the fold, the controls below. Twelve free original games inside.
Bitfold is a retro game console app for iPhone and iPad, made for iPhone Duo. It turns the whole screen into a pocket console — a glossy plastic shell, a pixel-sharp screen, a clicky D-pad, A and B, Start and Select, a power LED and a speaker grille — and it comes with twelve original games. No ads, no accounts, no tracking.
MADE FOR IPHONE DUO
Closed, it's a classic pocket console on the outer display. Open it and it becomes a Bitfold Duo: the game on the top half, the console's hinge drawn exactly over the real fold, controls and a companion screen below. Fold it like a book and the console opens into two pages. Your game keeps running through every change.
TWELVE BITFOLD ORIGINALS
Every bundled game is an original made for Bitfold, with its own music and characters: a platformer, a falling-gem puzzle, a vertical shooter, a pseudo-3D racer, a snake game, a block breaker, picture-logic puzzles, a pinball table, a top-down adventure, mini golf, a daily puzzle with a new harbor every day and a virtual pet to hatch and raise.
BRING YOUR OWN CARTRIDGES
Play backups of the cartridges you own (.gb, .gbc, .sgb, .cgb or .zip) from Files, AirDrop or the Bitfold folder in the Files app. Bitfold doesn't include or download any commercial games.
A SCREEN THAT FEELS REAL
Sharp pixel scaling, an optional pixel grid, dot-matrix shadows, LCD motion blur, and twelve palettes for monochrome games — from pea-soup green to amber and backlit blue.
TWELVE EDITIONS
Classic grey, Bubblegum, see-through Atomic purple with a circuit board inside, Lagoon, Dandelion, Berry, Kiwi, Ocean, Midnight, Glacier, Ivory and Champagne, each with a matching Home Screen icon.

Ratings & Reviews

New: Paper Harbor, the 11th Bitfold Original. A new harbor opens every day at midnight, the same for everyone. Each press of the D-pad is a gust of wind: sail every paper boat to its own pier in as few gusts as you can. Then share your result card (it never shows the harbor), keep your streak going and fill your stamp book.
New: Pockling, the 12th Bitfold Original. Pick one of six patterned eggs and hatch your own round little fluffball. It lives in real time: feed it, cuddle it, wash it, put it to bed, play with it and take it for walks while it grows up. It never dies and never runs away, it just misses you. Come back each day for a stamp in the book, and share its pet card.
Also in this update:
- Delete an imported game from its long-press menu on the shelf
- The shelf's text follows your Larger Text setting
- Games tapped in Bitfold's folder in the Files app open straight away
- A file in that folder that can't be imported now tells you so
- Zips with hidden files in them, like ones made on a Mac, now import the right game
- Files that aren't games are no longer added to the shelf
- The Continue card's last-played line no longer gets cut off
- A damaged save state no longer changes the game you're playing
