Unfold a second screen for your Mac.
Foldout turns your iPhone into a wireless extra display for your Mac. It’s made for iPhone Duo’s 7.6″ inner screen, and it works with any iPhone.
Free for Mac · macOS 14 or later · iPhone with iOS 17 or later
Fold it, unfold it, turn it.
Unfolded, iPhone Duo gives your Mac a 7.6″ display at full sharpness. Fold it and the display resizes to the outer screen; turn it sideways and it turns too.
It all happens in place, on the same connection, so your windows stay right where they were. On any other iPhone, the display fits its screen the same way.
- Resizes live when you fold or rotate
- No reconnecting
Pair once. Then just tap your Mac.
Setup takes a minute, and you only do it the first time.

Get Foldout for Mac
It’s free and lives in your menu bar. Allow Screen Recording and Accessibility when it asks: one sends the extra display to your iPhone, the other turns your taps into clicks.
-
Open Foldout on your iPhone
Your Mac shows up by itself, over your Wi‑Fi or a direct link between the two. Tap it.
-
Check the code, then click Pair
Both screens show the same 6-digit code. If they match, click Pair on your Mac. From then on, your iPhone connects in a couple of seconds, with no code.
A real display, wherever you are.
To your Mac, your iPhone is a real display, so your Mac’s keyboard and trackpad work on it too. Drag windows onto it, or arrange it in Displays settings.
No network? No problem.
Foldout uses your Wi‑Fi when both devices are on it. When they aren’t, it connects directly over the peer-to-peer Wi‑Fi link AirDrop uses, which also works on hotel and office networks that keep devices apart.
Private by design
After pairing, the picture and every tap are encrypted with a key only your iPhone and your Mac have. Devices that haven’t paired can’t connect. No account, no sign-in, no cloud.
Touch it like an iPhone
Tap to click and swipe to scroll, with the same glide. Pinch to zoom, touch and hold to drag, and pinch with three fingers to make text bigger or smaller.
Text you can read
Choose Sharpest, Larger or Largest on your Mac, and change it any time. Larger makes Mac text the same size as your iPhone’s own.
Your windows wait for you
Switch apps or lock your iPhone, and your Mac holds its display for 10 seconds. Come back in time and your windows are right where you left them.
Sharp and smooth
Your Mac makes a high-resolution display sized to your iPhone’s screen, and streams it with its hardware video encoder at up to 60 frames per second.
Lives in your menu bar.
Choose where the display sits next to your Mac, how big text looks on it, and the picture quality. Position and text size change right away, while you work.
Paired devices are listed in the same place, and you can forget one with a click.
Free to try.
Foldout for Mac is free. On iPhone, every feature works in free sessions of up to 5 minutes, which is plenty to see it working with your Mac.
