Set and respond to reminders on Apple Watch
Your Apple Watch notifies you of reminders you create in the Reminders app on your iPhone—and on any other iOS device or Mac that’s signed in to iCloud using your Apple ID. You can also create reminders with Siri on your Apple Watch. See iPhone User Guide for information about setting up the Reminders app on your iPhone.
Ask Siri. Say something like: “Remind me to pick up my dry cleaning at 5 PM.”
