Point your arm at a lamp, like you're showing it to a friend, and snap your fingers. It turns on.
Maestro Snap teaches your Apple Watch where your things are. You "paint" each device once by sweeping your arm at it, and from then on the watch knows what you're aiming at. It learns from your corrections, so it gets better with use.
No cameras, no hubs, no cloud. Works with Apple Home and Home Assistant. Free for one device, $8.99 one-time for the house.
