Headroom is a remote desktop for controlling a Mac from your iPad, iPhone, or another Mac. The big idea: nothing to install on the Mac. Turn on macOS's built-in Screen Sharing — that's the whole setup. WHEN YOU WANT IT • Drive the Mac in the next room from the couch • Manage a headless Mac mini — no monitor, no keyboard • Peek at your dev machine or build server from wherever you are • Reach your home Mac from anywhere over a VPN such as Tailscale WHY HEADROOM • Zero install on the Mac Connects straight to macOS's built-in Screen Sharing (VNC). No server app, no agent, no menu-bar daemon. • Finds your Macs automatically Macs on the same Wi-Fi appear instantly via Bonjour. Manual IP connections work too. • Fast, smooth screen Metal rendering plus ZRLE compression — feels real-time on a LAN and stays usable on thin connections. • Touch that makes sense on iPad and iPhone Tap to click, one-finger scroll, long-press to drag and select text, two-finger wheel scrolling, pinch to zoom. • Real mouse behavior on the Mac On a Mac (same app), clicks, drags, and right-clicks pass through 1:1. Option-scroll pans; Command-scroll zooms. • Full keyboard, and your voice Software and hardware keyboards both work. Modifier keys (⌘⌥⌃⇧) tap once for the next keystroke or double-tap to lock — every shortcut is reachable. Tap the mic on the keyboard and what you say is typed straight into the Mac. • Private by design Credentials live only in your device's Keychain, and passwords are encrypted in transit using Apple's standard Screen Sharing authentication. • Made for iPhone Duo Half open like a laptop, your Mac sits on the upper screen and the keyboard on the lower one. Fully open or held like a book, the Mac spans the inner screen; closed, the outer screen works on its own. Nothing is drawn across the fold. CONNECTED IN THREE STEPS 1. On the Mac: System Settings > General > Sharing > turn on Screen Sharing 2. Open Headroom — your Macs appear automatically 3. Sign in with the Mac's username and password. Done. HEADROOM PRO The free version limits connection time. Upgrade to Pro — a one-time purchase, not a subscription: • Unlimited connection time • Every future Pro feature included Buy once, use forever. REQUIREMENTS • Client: iPad / iPhone (iOS 17+, verified on iOS 27 and iPadOS 27), Apple Silicon Mac • Host: any Mac with Screen Sharing enabled (no extra software) • Same network; for internet access we recommend a VPN such as Tailscale — Headroom is built by MusicFlow ("music × engineering") — the tool we made to run our own headless Mac minis, polished into something we use every day.
