What it does

Any Command turns an Android phone into a second screen, trackpad, keyboard and gamepad for Windows. Stream one window to the phone and use it there while a film stays fullscreen on the monitor. Runs on your own network, or over Bluetooth with no PC install. Free tier, no account, and the PC app is a plain Windows install.
