SimBeam turns your iPhone or iPad into a live remote for the iOS Simulators running on your Mac. Pair the app with your Mac once by scanning a QR code, then connect any time to see all the simulators on that Mac, open any one of them, and watch its screen as a real-time video stream. Your taps, swipes, and the Home button are sent straight back to the simulator, so you can actually use it from your device β€” not just look at it. WHAT YOU CAN DO β€’ See every simulator on a paired Mac, with its iOS version and status β€’ Stream a simulator's screen live, with low latency β€’ Control it remotely β€” tap, swipe, and press Home β€’ Boot or shut down a simulator right from your device β€’ Jump back into recent simulators in one tap from the main screen β€’ Pair and keep multiple Macs, and switch between them any time BUILT FOR DEVELOPERS AND QA Test how a build feels in the hand without unplugging from your desk. Show a running simulator to a colleague across the room. Keep an eye on a long scenario from the couch. REQUIRES A MAC SimBeam is a companion to the SimBeam app on macOS. You need a Mac running the SimBeam companion with at least one iOS Simulator to pair with and stream from. Pairing is secure and takes a single scan. PRIVACY Your pairing identity stays on your device. SimBeam has no account to create, shows no ads, and does not track you.
