Hand off tasks from Apple Watch
Handoff lets you move from one device to another without losing focus on what you’re doing. For example, even though you can reply to email using the Mail app on your Apple Watch, you might want to switch to your iPhone so you can reply using the onscreen keyboard. Follow these steps to use Handoff.
Unlock your iPhone.
Double-click the Home button to show the App Switcher. (On iPhone X and later, swipe up from the bottom edge and pause to show the App Switcher.)
Tap the button that appears at the bottom of the screen to open the same item on your iPhone.
Tip: If you don’t see a button in App Switcher, make sure Handoff is turned on for your iPhone in Settings > General > AirPlay & Handoff.
Handoff is on by default. To disable it, open the Apple Watch app on your iPhone, tap My Watch, tap General, then turn off Enable Handoff.
Handoff works with Activity, Alarm, Calendar, Home, Mail, Maps, Messages, Music, News, Phone, Podcasts, Reminders, Settings, Siri, Stocks, Stopwatch, Timer, Wallet, Weather, and World Clock. For Handoff to work, your Apple Watch must be connected to your paired iPhone.
If you have a Mac with OS X 10.10 or later installed, you can also hand off from your Apple Watch to your Mac. For information about supported Mac models, see the Apple Support article System requirements for Continuity on Mac, iPhone, iPad, iPod touch, and Apple Watch.
