The notification alerts you add to your calendar on your iPhone or iPad will also work across all of your Apple devices, including your Mac.
If you want to create a new calendar event and set a reminder, tap + at the top-right to create an event instead.
If you’re creating a new event, just enter the info for your event, including the name, date, location, and other pertinent information.
You’ll be able to create two reminders for a single event. This is helpful if you want to be reminded before the event and at the time the event begins.
If you added an address to your event, your iPhone will also give you an automatic reminder when it’s time to leave. [1] X Research source
Open your iPhone’s Settings. Scroll down and tap Calendar. Tap Default Alert Times. Tap Events. Select a default reminder time.
If the “Allow Notifications” switch is gray or white, tap the switch to turn on notifications—the switch will turn green.
The Reminders app is geared toward reminders for things like To-Do lists, home projects, and other tasks that you don’t need to add to the Calendar app. Reminders you create in the Reminders app do not appear on your Calendar, but you will be able to access them on all Apple devices (including your Mac) on which you’re using the Reminders app. Read on to learn how to create a reminder in the Reminders app without Siri.
You can also enter a location that will appear when you receive the reminder. To set a reminder priority, tap the Priority option. Tap the back button when you’re finished.
