About this app

Xcode forces you to test on one simulator at a time. To check different screen sizes, you switch the simulator, rebuild, and run again. For every change. Minutes wasted, focus broken. MultiSim ends this loop. ONE BUILD, ALL SIMULATORS Press Ctrl+Shift+R to build once. MultiSim installs and launches your compiled .app on every booted simulator simultaneously. iPhone SE, iPhone 16 Pro, iPad Air: all updated at once. Up to 20x faster than the traditional approach. Press Ctrl+R to run across all simulators instantly without rebuilding. FOCUS STAYS IN YOUR EDITOR When you press Run in Xcode, the system moves focus to the simulator. You have to click back to return to your code. MultiSim runs entirely via global hotkeys: press Ctrl+R, all simulators update, your editor never loses focus. Optional sound notifications let you know when runs, builds, and cleans complete, without your eyes ever leaving the editor. If you do pixel-perfect UIKit development, this means hours of saved focus every day. SCROLL LIKE A REAL iPhone iOS Simulators don't respond to mouse wheel or trackpad scrolling natively. To scroll a list, a feed, or a web page, you have to click and drag. Every single time. MultiSim ends that. Your mouse wheel and trackpad become real touch gestures in every simulator window. Scroll naturally, just like you're holding a real iPhone. LIVE LOG VIEWER, PER SIMULATOR Each simulator's logs appear in a separate live tab. App logs only, or full iOS system output? Switch with one tap on the segment selector. Logs persist across builds. In Xcode, switching simulators means losing the previous console. In MultiSim, every log stays until the next build. Review history, compare, search, filter. Fling the dark floating window to any screen corner - it snaps automatically. Font size, opacity, and style are fully customizable.
