10 Best Calendar Apps for iPhone of 2026

Google Calendar is the best free calendar for most iPhone owners because it adds real capability over the built-in app without a subscription. Its App Store listing says it pulls flight, hotel, concert and restaurant reservations from Gmail onto the calendar, and it shows Google events beside the Exchange and iCloud calendars already set up on the phone, so you do not have to abandon an iCloud calendar to use it. Shared calendars let other people view, add or change events, and tasks sit next to events in the same view. Because the calendar belongs to a Google Account, it opens on any browser and on Android phones, which matters in households that mix devices. The limits are worth knowing. Google marks professional booking pages and working location as features that need Google Workspace or Google One AI Premium, and the iPhone app lists month, week and day views only. If you want natural language entry or a year view, look at Fantastical.

Fantastical is the strongest step up from Apple Calendar for people who live in their schedule. The free version already gives full screen day, week, month, quarter and year views, a three day weather forecast and task support that includes Todoist and Google Tasks. Its parser is the reason most people install it: type or dictate a phrase such as a repeating event on the third Thursday of every month and it builds the event, alert and calendar for you. Flexibits Premium adds Openings for sharing availability, Proposals for meeting polls, Zoom, Google Meet, Webex and Teams links, calendar sets that switch by location, templates and an Apple Watch app that works over LTE. It connects iCloud, Google, Exchange and Office 365 accounts. The catch is price: at $56.99 a year or $6.99 a month it is the most expensive app on this list, and several headline features sit behind the subscription. If you only need a clean free calendar, Google Calendar or Apple Calendar will do.

Apple Calendar is the baseline every other app here has to beat, and it is better than many people assume. The App Store listing says it shows events from iCloud, Exchange, Google and other accounts together in List, Day, Week or Month views, and reminders from the Reminders app now appear and can be completed right beside meetings. You can add a location to get a notification when it is time to leave, attach files and video call links, and share an iCloud calendar so family or colleagues can see, add or change events. Holiday, Birthdays and Siri Suggestions calendars fill in dates automatically, and you can subscribe to sports or TV calendars from the web. It costs nothing and has no in-app purchases. What it lacks is the extra layer that sends people looking elsewhere: no natural language parser, no year or quarter view, no booking links or meeting polls, and sharing is smoothest when everyone is on iCloud. If those gaps bother you, Google Calendar is the free upgrade and Fantastical the paid one.

Outlook belongs on this list because so many iPhone users carry a work calendar that lives in Exchange or Microsoft 365, and Microsoft's own app is the most direct way to see it. The App Store listing says Outlook for iOS works with Exchange, Office 365, Outlook.com, Gmail, Yahoo and iCloud, so one app can hold a work calendar and a personal iCloud calendar together. Calendar tools focus on meetings: you can share your availability with a tap and find times that work for others, and files from email, OneDrive and Dropbox open without downloading. Copilot can summarize long threads and draft replies, but only with a Microsoft 365 Personal or Family subscription or a business account with Copilot. The app is free, and Microsoft 365 Basic starts at $1.99 a month on the US App Store if you want the extra storage. The downsides: the listing flags advertising, and the calendar shares space with a full mail client, so it is busier than Fantastical or Apple Calendar.

Calendars by Readdle sits between Apple Calendar and Fantastical. Its App Store listing describes an all-in-one calendar, task manager, daily planner and habit tracker that runs on Mac, iPhone, iPad and Apple Watch and syncs with Google Calendar and iCloud. You get daily, weekly and monthly views, a built-in agenda planner, natural language entry for events and to-dos, color coding and widgets, and you can join Zoom, Google Meet or GoToMeeting calls straight from an event. Readdle has also added routines, habit tracking and a guided productivity course, which suits people who want one app for planning the day rather than only reading a schedule. Calendars PRO is listed at $3.99 a month on the US App Store, cheaper than Fantastical Premium's monthly price. The drawbacks are mostly about clarity: the in-app purchase list shows several yearly prices and separate add-ons such as recurring events, so it is hard to tell from the listing exactly what each tier includes. It also lists no quarter or year view.

Notion Calendar is the best free alternative for people whose work already lives in Notion. The iPhone app lets you attach Notion docs, projects and timelines to events, so meeting notes and deadlines show up next to the schedule. Notion's own FAQ says it currently syncs with Google Calendar accounts, Outlook calendars and iCloud-synced calendars, and it can show one unified view across several calendars and auto-block busy slots so personal and work events do not collide. Time zone handling is a highlight: you can pull in extra time zone columns to plan with colleagues in other cities. The App Store listing also describes six home screen widgets and a lock screen widget, and the website covers scheduling links that let others book time with you. It is free with no in-app purchases listed. The trade-off is focus. Without a Notion workspace much of its appeal fades, the iPhone listing leans on Google Calendar integration, and it does not describe a task list of its own.

TimeTree is built for the part of calendar life that Apple Calendar handles least well: coordinating with other people who may not all use iCloud. You create a calendar for a family, a couple or a group, invite members, and everyone sees and edits the same events. Each event has its own chat thread and can hold photos, so questions such as what time or where stay attached to the plan instead of scattered across messages. The App Store listing also describes shared memos and to-do lists for undated items, shared albums, notifications for updates, widgets and a web version, and it can copy or sync events from the device's other calendars such as Google Calendar. TimeTree says the app is loved by 75 million users worldwide. The free version shows ads, and its permissions list includes tracking for customized advertising. Premium costs $4.49 a month or $44.99 a year on the US App Store. Planning tools are lighter than Fantastical's, and the listing names iPhone and Apple Watch but not iPad.

Structured is not a classic calendar but a visual day planner, and it earns a place here because many iPhone users looking past Apple Calendar really want help planning the day. The app places tasks, events and routines on one timeline, so you can see how the hours fill up and drag blocks around. The free version includes the drag-and-drop timeline, an inbox for quick capture, sub-tasks with notes, a Pomodoro timer, Live Activities, widgets and sync across iPhone, iPad, Apple Watch and Mac. Accessibility options include VoiceOver, Voice Control and a dyslexia-friendly font. The important catch for calendar shoppers is that connecting your existing calendars and Reminders is a Structured Pro feature, along with recurring tasks, AI day planning and Replan, which moves missed tasks. Pro is offered monthly, yearly or as a lifetime purchase, but the US App Store listing shows many different Pro prices, so we left the price as pending. The listing cites 1.5 million active users.

Timepage is the pick for people who want their calendar to look good and tell them a bit more about the day. Bonobo's listing describes a timeline view for looking ahead, a month heatmap that shows busy and free days at a glance and more than 60 theme colors for the app, widgets and icon. Each day includes animated temperature and rainfall forecasts, travel time estimates for walking, cycling, driving or public transport, and hints such as how much free time you have before the next event. It works with any calendar already on the iPhone, including iCloud, Google, Outlook, Exchange, Yahoo and CalDAV, so there is no new account to set up. Membership costs $3.99 a month or $19.99 a year on the US App Store, the cheapest paid option on this list. The trade-off is that there is no free tier after the trial: if membership expires, the app becomes read-only and drops weather. Task tools are light compared with Fantastical or Calendars by Readdle.

Any.do is a to-do app first and a calendar second, which makes it a good fit for people whose day is driven by tasks rather than meetings. The App Store listing says it syncs in real time with the phone's calendar, Google Calendar and Outlook calendar, then lays events and tasks together in day, week and month views. Reminders can fire at a set time, when you reach a place or on a repeating schedule, and voice entry lets you add a task by speaking. Shared lists and assigned tasks cover household chores and grocery runs, and the app syncs across phone, web, desktop and tablet. Any.do says over 50 million people use it. The free Personal plan covers the basics, and Premium is $4.99 a month billed annually or $7.99 monthly on its pricing page, which lists location reminders among Premium features. As a calendar it is thinner than the others here, with no natural language parser for events like Fantastical's and fewer views.
