Pane makes your iPhone a real second display for your Mac — not a mirror, a genuine extra desktop you can drag windows onto. Over USB or Wi-Fi, at your phone's true Retina size.

One workspace · two surfaces
Everything, built in
No accounts, no paywalls, no tiers. Plug in — or stay wireless — and go.
Pane reads your iPhone's real panel — point size, native scale, safe areas — and builds the desktop to match. Switch resolutions live, without dropping the session.
Plug in for low-latency USB. Unplug and it falls back to Wi-Fi mid-session — the picture keeps going.
Tap, drag, scroll, right-click and pinch — as direct touch or as a relative trackpad, with haptics.
A genuine extra desktop, or a mirror of your main screen — and it remembers where you put it.
Power, media, volume, brightness and an app launcher, without leaving the couch.
Leave the app and the Dynamic Island keeps the controls one tap away.
Three decisions do most of the work.
VideoToolbox HEVC on the Mac, a hardware decoder on the phone. Frames never touch the CPU.
A direct usbmux tunnel skips the network entirely, which is where the latency normally goes.
The stream is strictly device-to-device. No cloud, no relay, no account, no telemetry.
