iOS 10's Home app is shown on an iPhone.

The Home app is a centralized control app for all of your HomeKit-enabled smart home accessories, from light bulbs to the smart lock on your door. From this app, you can control individual accessories, scenes with multiple appliances, and more. If you have a HomePod or two, you'll use the Home app to download and install software updates for the wireless speakers.

3D Touch all the things!

The Home app is a perfect example of 3D Touch's effectiveness.

Press (3D Touch) your accessories and Scenes within the Home app and from Control Center to make quick adjustments to temperature, color, brightness, etc., depending on the accessory.

Tip: Press (3D Touch) the Home app on your Home screen to change between Scenes.

Favorites

When you launch the Home app, you're presented with a page of curated Scenes and accessories called Home. These are your Favorite Scenes and Favorite Accessories.

In contrast, the Rooms page shows you all of your HomeKit-enabled accessories, not just your favorites.

Rooms

Rooms are bound to be familiar to anyone who's used HomeKit-enabled accessories in the past. Rooms contain your various HomeKit-enabled accessories — you're encouraged to organize your accessories according to which room they're physically in.

My living room, for example, has three Philips Hue lights and an Ecobee Smart Thermostat. The Home app will also display the Scenes that include the Accessories in your specific room.

Status and Notifications

When you launch the Home app (to the Home page), you'll see your home's name big and bold near the top of the screen. The text below your Home's name is your Home's status.

The status provides an overview of what your HomeKit-enabled accessories are up to. With a quick glance, you can see how many lights are on, the temperature, and more.

You can also enable notifications for certain HomeKit-enabled accessories. In iOS 12 and macOS Mojave, you can adjust the notifications that you receive for individual accessories.

Wallpapers

The Home app lets you personalize the app with custom wallpapers for your Home and your Rooms. If you have multiple houses with HomeKit-enabled accessories, custom wallpapers can help you quickly differentiate between homes. It's also an easy way to differentiate between Rooms within a home.

Home Notes

Home Notes are a little like the dry-erase board on the fridge, or the guest book in an Airbnb location.

If you input notes in the Home Notes section of the app, everyone who's a member of your shared home will be able to see the notes. You can set ground rules (hello, Airbnb hosts), let your kids know you popped out to get groceries, or troll your significant other — the choice is yours.

Automation

"When I leave the house, turn off my bedroom lights and turn up the thermostat."

"If my smoke detector senses smoke, turn on all my lights and set them to red."

Those are just two examples of the tasks you can create with Automation. Ultimately, it's exactly what it sounds like: A way to automate your smart home, based on various triggers and corresponding outcomes.

Home Hubs

Many HomeKit-enabled accessories already offer some form of remote access, but if you'd rather control your lights, thermostat, switches, etc. from one app (the Home app), Home Hubs make that task easier.

Your Apple TV, iPad, and now HomePod can act as a Home Hub, allowing you to set up automations, access your Accessories from remote locations, and more.

macOS

Beginning with macOS Mojave, the Home app is also available on the Mac. Part of Apple's initiative to make it easier to bring iOS apps over to macOS, the Home app for Mac features the same functionality that you'll find in its iOS counterpart, from control over individual accessories to managing rooms and scenes.

Update September 2018: Added new screenshots, and information about what's new in the Home app in iOS 12 and macOS Mojave.
