Any window from your Mac, on your iPhone and iPad. Sill shows a window from your Mac, or the whole desktop, on your iPhone or iPad. You use it there with touch, a trackpad, a keyboard or Apple Pencil. Sill for Mac captures the window, encodes it as HEVC video and sends it to the Sill app on your device.

Your Mac and your device connect on the same network, over a USB cable, with Direct Wireless Connection when they share no network, or through your own VPN, such as Tailscale, with Remote Access.
