The Apple Vision Pro does not have a native version of the company's Home app. You can start the iPad version in compatibility mode, which I'm glad is available, but that means it doesn't offer any spatial computing features outside of a window floating in your environment. Fortunately, Rob Owen's HomeUI fills the gap with a native visionOS app focused on lighting, sockets and switches. The special feature of HomeUI is that you can create small windows for individual lights, sockets, switches and scenes that you can place in your environment. For example, you can have a control for your bedroom lighting hanging on the bedroom wall and your kitchen lighting floating above a countertop. HomeUI's controls are easy to set up. The app features a main window with the rooms you've set up in the Home app in a sidebar so you can navigate by room. The rest of the window contains tiles for your lighting and electrical outlets. I also have a smart button in my office that showed up in HomeUI, which I think was a light switch, but the app couldn't control it. Tap a lamp or socket and it will appear in its own customizable window. Tapping the lamp's light bulb icon turns the light on and off, while the slider below the window lets you control the brightness in 10% increments. You can pinch hold the slider to move it up and down the brightness scale, or you can glance at a spot along the slider scale and tap to jump to that spot. I tested HomeUI with lights and sockets, but no switches because I didn't have any installed, and in my testing the app worked incredibly well with very little latency between the moment you tap a button and your accessory's response. Along the left edge of HomeUI's main window is a tab bar that lets you switch to scenes, which works the same way as devices, except instead of choosing from a window full of tiles, you can choose from a list of scenes. From the tab bar you can also switch to a handful of settings for the app. Owen says more types of accessories will be added to the app over time, which I'm looking forward to. There are also some layout issues that could be improved. The icons in device windows are cropped based on the corner radius of the window, and the tiles in the main window are often arranged in rows with different numbers of devices for no apparent reason, but those are minor details that don't affect the usefulness of the app. Finally, I would love it if the status of a lamp or other device was reflected not only in the individual window, but also in the main window of the app. As someone who is used to controlling my HomeKit devices via widgets all day long, I immediately turned to HomeUI. It took time to get used to being able to place the controls for my lights and outlets in my physical space, but once I did, HomeUI became indispensable. With just a few taps, I can look at a HomeUI window and control my lights and the outlets I use. It's a great experience and I look forward to using it more often as new device types are added to the app. HomeUI is available on the App Store for $9.99.
