DuoBook: Pocket Laptop
Your Mac’s screen + keyboard
Only for iPhone
Free
iPhone
Fold your iPhone Duo like a laptop: your Mac’s screen on top, a full keyboard and trackpad below. Try the built-in demo, no Mac needed.
DuoBook turns your iPhone into a tiny laptop for your Mac. Fold iPhone Duo like a laptop: the top half shows your Mac’s screen, live, and the bottom half becomes a full keyboard and trackpad that control it.
Made for iPhone Duo, it follows the hinge as you fold: laptop, or flat with a big trackpad. Closed, the outside screen is a laptop lid you design yourself: color, finish, your initials or a photo, even a glowing mark. It also works on any iPhone with iOS 17 or later.
A FULL KEYBOARD
• Every key, laid out like a Mac laptop, with a top row for brightness, Mission Control, Spotlight, dictation, Do Not Disturb, media, and volume
• Hold ⌘ ⌥ ⌃ ⇧ while you type, tap one to apply it to the next key, or double-tap to lock it
• The Touch ID key locks your Mac
• Real key click sounds and haptics
• Pair a Bluetooth keyboard with your iPhone and it types on the Mac too
A REAL TRACKPAD
• Tap to click, two-finger tap to right-click, drag, scroll with momentum, pinch to zoom
• Three- and four-finger swipes for Mission Control, App Exposé, and switching desktops
• Or touch the Mac’s screen directly
YOUR MAC, FROM ANYWHERE
• At home it finds your Mac on Wi-Fi in a blink
• Away from home it reaches your Mac over the internet. Turn on “Access from anywhere” in DuoBook Host: it sets up most home routers automatically and keeps your Mac’s address in your own iCloud
• Pair once with a 6-digit code shown on both screens. Every connection is encrypted end to end
MORE
• Hear your Mac’s sound on your iPhone
• Copy on the Mac, paste on the iPhone, and send your iPhone’s clipboard to the Mac
• Send photos and files to the Mac’s Downloads folder
• Choose which display to show on Macs with more than one
• Six themes, four app icons, and a lid you can customize
• A built-in demo Mac, so you can try everything before setting up
WHAT YOU NEED
• A Mac with macOS 14 Sonoma or later, running the free DuoBook Host app from mehdichitsaz.github.io/duobook/mac
• On the Mac, allow Screen Recording and Accessibility for DuoBook Host (it shows you how)
