Sill puts your Mac on your iPhone and iPad. Pick any window, or the whole desktop, and use it with touch, a trackpad, a keyboard or Apple Pencil. Your apps keep running on your Mac. Sill shows them and sends back what you do. Sill needs the free Sill for Mac on the Mac you want to use. Get it at getsill.app. It runs on a Mac with macOS 14 or later. Get started • Open Sill for Mac and allow Screen Recording and Accessibility. • Open Sill on your iPhone or iPad. Your Mac shows up. Tap it. The first time, scan the code your Mac shows. • Pick a window from the Apps list, or tap Desktop to see the whole screen. • The first time, a short tour shows you the controls. Made for touch • Tap to click. Touch and hold to right-click. Drag to scroll. • Apple Pencil works as a mouse, with hover on iPad models that support it. • Hold your device upright for a laptop layout: the picture on top, a trackpad and a row of keys below. On iPhone, turn on Larger Picture to give a window’s picture more of the screen. • On iPhone Duo, open it flat and your Mac fills the inner display. Half open, it’s a laptop: the picture above the fold, a trackpad and keys below. Closed, Sill runs on the cover display. • Type with the on-screen keyboard, or on a hardware keyboard as soon as you connect, with shortcuts and Esc. A trackpad or a mouse scrolls the window under the pointer. • Copy text on your Mac and paste it on your iPhone or iPad. To paste on your Mac what you copied on your device, tap Paste in Sill: it goes where your Mac’s cursor is. • Swipe and pinch with three fingers for Mission Control, App Exposé, Spaces, Apps and Show Desktop. • Use the menus of the app you’re in: tap Menus in the bar, or on iPad with iPadOS 26 or later, use the menu bar at the top of the screen. • Switch windows from live thumbnails in the bar.

Turn on Direct Wireless Connection on the Mac and connect straight to it. • Pair each device with your Mac once by scanning a code. Over a USB cable it pairs by itself. By default your Mac lets in only the devices you paired, and every connection is encrypted. • Away from home, reach your Mac through your own VPN. Sill starts at a quality a slower connection can carry, tells you when the connection can’t keep up, and moves back to your home network by itself when you get home. Private • No account, no ads, no tracking. • Sill has no servers and collects no data. The picture and what you type go between your devices and your Mac, and to no one else. • Sill is free and open source (Apache 2.0): https://github.com/Saffsanity/sill Good to know • Sill shows one window, or the whole desktop, at a time. • Sill for Mac comes from getsill.app, not the Mac App Store.
