The best calendar app for iPhone

The right pick depends on which account your events live in and who you share them with. Here is a plain comparison.

Apple Calendar

Built into every iPhone and syncs through iCloud to iPad, Mac and Apple Watch. It can also show Google, Exchange and Outlook.com accounts side by side. It is the simplest choice if your family is on Apple devices, and iCloud calendars can be shared with others.

Google Calendar

A good fit if you use Gmail or Google Workspace or share calendars with people on Android. The iPhone app has month, week and schedule views. You can also add your Google account to Apple Calendar instead of using a separate app.

Microsoft Outlook

Combines mail and calendar in one app and is often what workplaces use with Microsoft 365. Some employers restrict which apps a work account can use, so check your company's rules.

Fantastical

A paid third-party app known for typing events in plain language and for its design. It works with iCloud, Google and Exchange calendars.

How to choose

• Mostly Apple devices: Apple Calendar.
• Gmail or Android in the family: Google Calendar, or add Google to Apple Calendar.
• Work on Microsoft 365: Outlook, if your employer allows it.

The part no calendar app solves: typing it all in

Every calendar app still expects you to type in each date. Snap to Calendar works alongside Apple Calendar: snap a photo or screenshot of a schedule, flyer or invite, review the events it finds, and save the ones you approve. A whole printed season schedule can go in at once.
