MainVac

MainVac brings a single app window from your Mac or Windows PC to your iPhone or iPad: tap, scroll, zoom and pan, compose text, and send keyboard shortcuts. Install the compatible desktop companion from https://mainvac.com/ and keep your computer awake and reachable. MainVac is free, with no MainVac account or in-app purchases. For developers, MainVac shows how an app or web page runs on your computer. Interact with a supported simulator remotely, without installing that development build on your phone. MainVac itself does not provide an AI service. You can also work with documents and other applications on your own computer. Input support depends on the application and the permissions granted on the host. REMOTE APPS MainVac sends only the app window you need to your phone, scaled, fitted to your screen and cropped. With remote window switching allowed, you can move to other apps from your phone; turn it off and your phone sees only the window you selected. You decide the permissions. INTUITIVE CONTROLS • Tap to click, long-press to right-click, swipe to scroll • Pinch to zoom and drag to explore the details • Tap a text field to type, double-tap to select text, with extra keys to help edit text • Configure your own shortcuts for each app on your computer and supercharge remote work SCREEN PRIVACY MODE Set a privacy password on the computer and enable Screen Privacy Mode to cover its local display while continuing an allowed remote session. This is not an operating system lock. The effect depends on the display and system capabilities; hardware and input limitations are explained in the desktop app. SECURITY AND PRIVACY MainVac takes your privacy seriously. Permissions are yours to configure, and security is at the core of MainVac. SWITCH AND LAUNCH Open the remote window bar to switch between permitted windows or launch available desktop apps. These actions depend on the host's window-switching and remote-launch settings. PICTURE IN PICTURE Use Picture in Picture for a read-only preview while using another app, when supported by the device and its settings. Return to MainVac to control the window. CONNECT YOUR WAY • Quick Connect: scan the invitation QR code in MainVac on your computer. No account needed, works across networks • Local network: discover nearby computers automatically on the same network, or enter an address to connect directly • Tailscale: use the separate Tailscale app on your phone and join a network that can reach the computer. This requires your own Tailscale or Headscale setup
