A trackpad, not a tiny desktop
Most remote-desktop tools on a phone make you poke at a 27-inch desktop scaled onto a 6-inch screen. The viewer's touch mode works like a laptop trackpad instead: one finger drives an accelerated pointer with a visible cursor — precise enough to hit a menu item on a 4K display. Tap to click, two fingers to scroll, pinch to zoom, and the view follows the cursor as you go.
Typing and shortcuts that actually work
The on-screen keyboard sends real keystrokes to macOS — including backspace, return, and composed characters. Modifier keys (⌘ ⌥ ⌃ ⇧) latch so you can type ⌘C with two taps, and a toolbar menu fires Mission Control, Spotlight, screenshots, app switching, volume, and Force Quit as single taps.
Multiple displays, one thumb
A Mac with two or three displays shows them as switchable views — tap a display number in the toolbar and the viewport crops to it. No panning across a 7000-pixel-wide stitched desktop.
Nothing to install
It's a web page. Safari on iOS, Chrome on Android — if it renders a canvas, it drives your Mac. (A native iOS and Android app is in the works for tighter gestures and background reconnects.)
