DuoBook turns your iPhone into a MacBook for your Mac: your Mac's screen, live, on top, with a full Mac keyboard and trackpad below. On Apple's iPhone Duo it folds like a tiny laptop; on any other iPhone with iOS 17, it's all on one screen.
DuoBook puts your whole Mac on your iPhone: check a long build from the couch, fix something on the Mac mini plugged into the TV, work from the other room without carrying the laptop.
If you had your Mac in your pocket, what's the first thing you'd actually use it for?
DuoBook turns your iPhone into a MacBook for your Mac: your Mac's screen, live, above a full Mac keyboard and trackpad that control it. On Apple's iPhone Duo it folds like a laptop, and the outside screen becomes a lid you design. Free, no account, encrypted end to end.
