Windows and simulators

Your simulator, full screen in your hand.

Your agent just built the app. Open the iOS simulator or Android emulator running on that host straight from the terminal, full screen on your iPhone, and tap through the change while the agent keeps going. Or pick any window on the Mac and work in just that window.

What you can do

01

Simulators, straight from the source

With Xcode 27 or later on the Mac, Warpeer shows a booted iOS simulator directly from the simulator itself: no Simulator window, no Screen Sharing, just the device screen, sharp and live. Android emulators and USB devices come through adb the same way.

02

Touch it like the device

One finger is a finger: tap, swipe and long press. Two fingers pan and a pinch zooms. The key bar turns into the device’s own keys, Home, Lock and Rotate on iOS and Back, Home and Recent Apps on Android. Text you type arrives as typed; an iOS simulator takes Chinese and emoji too.

03

It finds you in the terminal

When the host of your terminal tab has a booted simulator or a running emulator, a ball with a count floats over the terminal. Tap it to see each device with a screenshot, iOS and Android apart, and open one in a tap. Drag the ball anywhere out of your way; it stays where you leave it.

04

One window, the whole screen

Tap Windows in a remote desktop to see every window on the Mac as a card, simulators first. With screen recording allowed on the Mac, each card shows the window’s title and its own uncovered picture. Pick one: its app comes forward and your iPhone locks onto that window, follows it when it moves and returns to the whole desktop when it closes. Warpeer never resizes or moves your windows.

Good to know

An advanced feature, free during Early Access. The window list and iOS simulators need a Mac. A simulator without Screen Sharing needs Xcode 27 or later; with an older Xcode Warpeer shows the device screen inside the Simulator window through Screen Sharing. Android devices need adb on the host, which Android Studio installs. An Android screen refreshes a few times a second, made for checking and tapping, not games. Nothing new is installed, and screens travel only inside your SSH connection.
