With Continuity, you can use your iPad together with your iPhone, Mac, and Apple Watch to work smarter and move seamlessly between your devices.
Continuity is the way that your Apple devices work together. There are many Continuity features that allow you to easily work across your Apple devices, without ever missing a beat. There’s no specific Continuity app—it’s built into the operating system and many apps you use every day. You just need to be System requirements for Continuity features on Apple devices.
You can easily share content between your devices, whether it’s copying text on an iPad and pasting it your Mac, sharing a file from your iPhone to your iPad, or handing off tasks between devices.
Quickly share photos, videos, contacts, and anything else, with anyone near you—wirelessly. AirDrop makes sharing to iPhone, iPad, and Mac as simple as dragging and dropping. See Use iPhone to allow calls and text messages on your iPad.
If you have an iPad (Wi-Fi + Cellular), you can share internet using the Personal Hotspot on your iPad when you’re within range of your Mac (and other devices)—no setup is required. Your iPad automatically appears in the Wi‑Fi status menu—just select it to connect to the internet. See Use FaceTime on Apple TV 4K (2nd generation or later).
When your Mac is near an iPad, Universal Control allows you to use a single keyboard and trackpad, or a connected mouse, to work across the devices. You can even drag content between them—for example, you can sketch a drawing with Apple Pencil on iPad, then drag it to your Mac to drop into a Keynote presentation.
