Maestro Snap lets you control your smart home with Apple Watch. Point at a light and snap your fingers to turn it on or off. Connect Apple Home or Home Assistant, then teach Maestro where you point for each device by sweeping your arm toward it. You can use a finger tap instead of a snap and correct a wrong selection on the watch. Control supported lights, switches, plugs, fans, blinds, TVs, and scenes. Locks and garage doors need a confirmation tap. Add a Maestro complication to your watch face to open the app quickly. On watchOS 11 or later, the Routine Favorites widget puts up to three suggested or pinned devices in the Smart Stack, so you can control them without opening Maestro. One device in one room is free. Maestro Unlimited is a one-time purchase for more devices and rooms, webhooks, and extra color schemes, snap effects, sound sets, and app icons. Pointing recognition runs on the watch, with model backups sent to your paired iPhone. No Maestro account is required. The app has no advertising or analytics SDKs. If you send a support report, we receive your message and any diagnostics you include. Details: https://maestrosnap.com/privacy.html Requires Apple Watch Series 5 or later, including SE and Ultra. Open Maestro on the watch to use gestures. Recognition can miss, especially during initial setup.
