I’ve used Apple’s Calendar app for years, despite compelling third-party alternatives on the App Store, and one key iOS feature is a great example of why I’d have a hard time switching.

When comparing calendar apps, there are plenty of third-party options that offer more features than Apple Calendar.

Fantastical is a personal favorite. It excels at offering power user tools like scheduling, calendar sets, and more. Many iPhone users stick with Google Calendar or perhaps Outlook because they’re more custom-built for those calendar services.

But in a similar way, Apple’s Calendar app is designed to pair especially well with the iPhone and iOS—and has an exclusive system feature I use a lot.

Whenever someone sends a proposed meeting date and time, iOS recognizes that and Apple Calendar lets you take action on it.

This uses the iOS ‘data detectors’ system, which tags certain types of text on your iPhone as actionable.

When calendar dates are detected, you can tap the text to see a menu with the following options:

Add to Calendar

Add to Reminders

Show in Calendar

Copy Event

I use this feature all the time to quickly, conveniently manage my schedule.

My two go-to actions from the menu are ‘Show in Calendar’ and ‘Add to Calendar.’
