What is the best calendar app for iPhone?

Apple Calendar, for most people. It's free, already installed, and shows every calendar account you add in one view. If you add plans by typing all day, get Fantastical.

Is Apple Calendar or Google Calendar better on iPhone?

Apple Calendar if everyone you plan with has an iPhone, and Google Calendar if anyone uses Android or your email is Gmail. You can also add your Google account to Apple Calendar and keep one app.

What is the best free calendar app for iPhone?

Apple Calendar. Google Calendar and Outlook are free too, as is Notion Calendar. Fantastical and Cozi have free versions with limits; Cozi's free version stops at 30 days ahead.

Is Fantastical worth paying for?

Only if you'll use what the paid plan adds, such as travel time and the Apple Watch app. Typing a plan in one sentence is already in the free version. The Individual plan costs US$6.99 a month or US$56.99 a year.

Which calendar app is best for a family?

Cozi, if you want the shopping list in the same app or someone in the family uses Android. If everyone has an iPhone, a shared iCloud calendar in Apple Calendar does the job for free.

How do I add Google Calendar to my iPhone calendar?

Open Settings, tap Apps and then Calendar, and under Calendar Accounts use Add Account to sign in to Google. Your Google events then show in Apple Calendar beside your iCloud ones.

9 best calendar apps for iPhone in 2026, free and paid

How we chose

The best calendar app for iPhone is the one you open and believe. For most people that's Apple Calendar, which came with the phone. A new app has to beat it at something you do daily, or it becomes one more icon you forget about.

What makes a calendar worth keeping? A plan goes in within seconds and comes back on the right day with an alert, and the people you share plans with see it as well. We held every app to six questions:

What does it cost, and what does the free version leave out?
Which accounts can it read? Most people juggle at least two, say iCloud for home and Google or Outlook for work.
How fast is a new event? One typed sentence beats four fields.
Do tasks sit on the same screen as events?
Does it run anywhere else you need it, such as an iPad, a Mac, or the Android phone your sister carries?
What does it do better than the app you already have? No answer meant no place on the list.

We read every price and feature on the maker's own website, help pages or App Store listing on 29 October 2026. Nobody here tested these apps by hand. That's why you won't find star ratings or speed scores. Prices are US dollars, from the US App Store or the maker's site, and other countries' stores charge their own amounts.

The 9 best calendar apps for iPhone

Start with the free app on your phone, since most people never need to replace it. Each pick after it wins at one job, from typing a plan in a line to running a family.

1. Apple Calendar: best for most people

Apple Calendar comes with your iPhone and costs nothing. It pulls in your iCloud and Google accounts, plus Exchange and others, and puts them in one view. To add your Gmail, open Settings and tap Apps, then Calendar.

Two features cover jobs that once needed a second app. Reminders you've given a date show up inside the day, and you tick them off right there. You can also share an iCloud calendar with your partner and let them add or change events.

Pick it if you want every calendar you own in one free view. Skip it if the people you plan with don't use iPhones. Apple's sharing page covers sharing with other iCloud users, and anyone else gets a read-only public link.

2. Fantastical: best for typing a plan in one sentence

Fantastical turns a sentence into an event. Type "Coffee with Jo at 10 Saturday" and the day and time fill themselves in. Start with "todo" or "remind me to" and you get a task instead. It reads iCloud, Google and Exchange calendars, and it pulls in Todoist and Google Tasks.

Flexibits' pricing page keeps the typing and the tasks in the free version. Pay for the Individual plan and you get travel time with leave-now alerts, the Apple Watch app, event templates, and calendar sets that switch when you arrive at work. That costs US$6.99 a month or US$56.99 a year after a 14-day free trial. The Family plan is US$10.49 a month.

Pick it if you add several plans a day and want each one done in a line. Skip it if travel time or a Watch app is your only reason to pay. Apple Calendar already has a time-to-leave alert, and it runs on Apple Watch for free.

3. Google Calendar: best if your plans already live in Gmail

Google Calendar's iPhone app is free. Flight and hotel bookings from Gmail land on it by themselves. Shared calendars let other people see your events, add their own or change them, and your iCloud events show alongside the Google ones.

It's the easy choice for a mixed household. Google makes the app for Android as well as iOS, so your sister on her Android phone sees the same shared calendar you do. Booking pages and a working-location setting need a paid Google Workspace or Google One plan.

Pick it if your email is Gmail or anyone you plan with uses Android. Skip it if everything sits in iCloud. Apple Calendar shows the same events with one app fewer. Keep work and personal calendars apart? There are three ways to sync work and personal calendars so you see both at once.

4. Calendars by Readdle: best for tasks and habits next to events

Readdle's Calendars puts your to-dos on the same screen as your events. It syncs Google Calendar, Outlook, Exchange and iCloud, along with Apple Reminders and Google Tasks. Type "Swim with Mia Tuesday 7am" and you get an event. A habit tracker and a mood log sit beside the calendar, and the app runs on iPhone, iPad, Mac and Apple Watch.

The download is free, and Calendars PRO costs US$3.99 a month or from US$19.99 a year on the US App Store.

Pick it if you want tasks beside events for US$19.99 a year, against Fantastical's US$56.99. Skip it if all you want is a calendar, since the habit tracker and the mood log come with the app whether you open them or not.

5. Microsoft Outlook: best if your work email is Outlook

Outlook is a mail app first. Outlook for iPhone is free and keeps a calendar inside it, and it works with Exchange and Outlook.com as well as Gmail and iCloud accounts. When someone asks to meet, you can share the times you're free with a tap. The Copilot features need a paid Microsoft 365 plan.

Pick it if your job runs on Outlook and the meeting invites arrive there. Skip it if you'd like a calendar with no inbox attached. Outlook keeps both in one app.

6. BusyCal: best if you won't pay a subscription

BusyCal for iPhone costs US$9.99, once. It reads iCloud, Google and Microsoft 365 calendars plus any CalDAV server, and a dated task stays on the calendar until you finish it. You type events the way you'd say them. A pinch stretches the week view from 2 to 14 days, and Face ID can lock the calendar sets you choose.

The Mac app is a separate purchase. BusyMac sells it for US$49.99, or inside a Setapp subscription.

Pick it if you want typed events and tasks for one payment. Skip it if you'd also want it on a Mac and won't spend another US$49.99.

7. Structured: best for seeing your day as one timeline

Structured draws your day as a single line from morning to night. Tasks and routines sit on it in order. The free version gives you that drag-and-drop timeline with a focus timer, and it syncs across your Apple devices.

The catch: connecting the calendars you already have is a Pro feature, and so are repeating tasks. Pro is sold by the month, by the year or for life, and lifetime costs US$99.99 on the US App Store.

Pick it if you plan in blocks, like a study hour, and want to see the whole day at once. Skip it if you'll stay on the free plan, because your calendar events won't appear on the timeline. If blocking time is the real reason you want a new app, look at the best time blocking apps too.

8. Cozi: best for a family calendar

Cozi is a shared organiser for a household. Everyone gets a colour on one calendar, and the grocery list and meal plans live in the same app. The family shares a single account, and Cozi works on iPhone and Android as well as in a browser. A work or school calendar can show up in it through a subscription.

The free version carries ads. It also won't let you add, edit or view events more than 30 days ahead. Cozi Gold lifts that limit, drops the ads and adds a month view on phones. Gold costs US$29.99 to US$39 a year on the US App Store.

Pick it if you run the family calendar and want the shopping list beside it. Skip it if you book holidays months ahead and won't pay, since the free version stops at 30 days.

9. Notion Calendar: best if you already plan in Notion

Notion Calendar is free. It puts your Notion pages and project dates next to your events, and Notion's FAQ says it syncs Google, Outlook and iCloud calendars. Its App Store listing marks it iPhone only. A tablet version is still in the works, the FAQ says.

Pick it if your to-do lists and projects already sit in Notion. Skip it if you don't use Notion. You'd be left with a tidy free calendar, and Apple Calendar is already one.

What each one costs

Prices are in US dollars as of 29 October 2026. Where an app sells several plans, the Paid column has the smallest single payment. Paying by the year costs less per month for Fantastical and Calendars.

App	Free version	Paid	Also on
Apple Calendar	Everything	None	iPad, Mac, Watch
Fantastical	Typing, tasks	US$6.99 a month	iPad, Mac, Watch
Google Calendar	Everything personal	Workspace extras	Android, web
Calendars	Yes	US$3.99 a month	iPad, Mac, Watch
Outlook	Mail and calendar	Copilot plans	iPad, Watch
BusyCal	No	US$9.99 once	iPad, Watch
Structured	No calendar sync	Several; US$99.99 for life	iPad, Mac, Watch
Cozi	30 days ahead, ads	US$29.99 a year	Android, web
Notion Calendar	Everything	None	Android, Mac

Five of the nine cost nothing for what most people need. Four are free outright, and Fantastical's free version keeps the typing. What money buys is extras: travel alerts and a Watch app in Fantastical, or your calendar on Structured's timeline.

Which one fits your day

Match the app to a habit you already have. The longest feature list rarely wins.

You want it free and simple: Apple Calendar, with your Google or Outlook account added.
You add plans all day by typing: Fantastical, or BusyCal if you'd rather pay once.
Someone you plan with uses Android: Google Calendar.
Your job runs on Microsoft: Outlook.
Your tasks matter as much as your events: Calendars by Readdle. If tasks matter more, start with a task app and let it feed your calendar.
You block out the day hour by hour, gym and study included: Structured.
You run a family: Cozi, or a shared iCloud calendar when everyone has an iPhone.
Your projects live in Notion: Notion Calendar.

Most people end up with one app to look at and several accounts feeding it. The family iCloud calendar and the football club's fixtures can both sit next to your work calendar. So choose the app you'll open first thing, then point everything else at it.

Set up Apple Calendar before you replace it

Ten minutes in Settings fixes most complaints about the built-in app. Do these six things, then live with it for a week before you shop for another:

Open Settings, tap Apps and then Calendar, and under Calendar Accounts use Add Account to sign in to Google or Microsoft Exchange with the same login you use on your laptop.
Choose a Default Calendar.
Under Default Alert Times, give events their own alert, and turn on Time to Leave if you drive to things.
In the Calendar app, open the calendar list and select Scheduled Reminders, and timed reminders will sit at their time in the day.
To share a household calendar, tap the info button beside an iCloud calendar and use Add Person, then decide who gets Allow Editing.
Give each calendar a colour. Apple's page on multiple calendars notes one exception: a Google calendar keeps the colour Google set.

After the week, notice what you still wish it did. If you wish you could type plans in a line, try Fantastical. If you wish the family could see them, try Cozi. A calendar also works better with a plan for the day behind it, so build a daily schedule to go with it.

Your calendar holds the events. ActivityTracker's Plan my day takes the tasks that are due and puts them in the free gaps around your Google Calendar events, inside your work hours.

One week, one calendar, no missed pickups

Made-up example: Lena teaches piano from home and studies for an accounting exam two evenings a week. She shares school pickups with her partner, Marco. Her lessons sit in a Google calendar that students book into, and the family plans live in her head.

On Sunday she adds her Google account to Apple Calendar. Then she makes an iCloud calendar called Home and shares it with Marco, editing on, and sets a 30-minute alert for every event.

On Monday Marco adds Thursday's parents' evening to Home from his own iPhone, and it turns up on hers in the Home colour.

Tuesday brings a change. A student moves a lesson to Wednesday at 4pm, Lena drags it to the new slot in Apple Calendar, and the move goes back to her Google calendar.

Three days in, she has typed eight new plans in a day, so she tries Fantastical's free version. "Study chapter 3 Thursday 8pm" goes in as one line.

On Friday she reads the week back: 23 lessons, 2 study blocks, one parents' evening, no missed pickups. She keeps Apple Calendar for the family view and Fantastical for typing. Both read the same calendars.
