Quick comparison table

Google Calendar is a versatile everyday choice, with customizable views and widgets. Any.do and Calendars: Schedule Planner add task and planning tools, while Fantastical brings together events, tasks, and meeting scheduling. Calendar gathers accounts in one place, and Simple Calendar keeps things pared back. Google Calendar and Any.do are the Android options; the other four are for iOS.

1. Google Calendar

Best for: Android users who want an everyday calendar with flexible views.

Google Calendar lets you create events and sort them across multiple calendars, keeping personal commitments separate from other parts of your schedule. Its customizable views and widgets are particular strengths. You can check your plans in the app or on your device’s home screen, and task support gives you another way to track what needs doing. There’s plenty of room to organize things, though the best view and setup depend on how you like to plan.

2. Any.do - To do list & Calendar

Best for: Android users who want tasks and calendar events together.

Any.do brings calendar events together with to-do lists, reminders, notes, and checklists. Its main appeal is having appointments and tasks in one planner instead of managing them separately. The extra tools can be useful if you like turning plans into reminders and checklists. But if you just want a clear view of upcoming events, Any.do’s wider focus on tasks may be more than you need.

3. Calendar

Best for: iPhone users who want to bring several calendar accounts together.

Apple’s Calendar app puts events from different calendar accounts in one place. You can view your schedule as a list or by day, week, or month, then create events and send invitations. Shared calendars are handy for coordinating plans with other people. The app stays focused on events, making it a straightforward choice if you want to manage commitments across accounts without adding a separate set of task-planning tools.

4. Calendars: Schedule Planner

Best for: iOS users who want a calendar alongside personal planning tools.

Calendars: Schedule Planner pairs event scheduling with reminders, tasks, and habit tracking. It also syncs with services such as Google Calendar and iCloud, which is useful if your schedule already lives in either one. The mix of calendar and personal planning tools lets you keep events, routines, and tasks together. That can suit people who want more than event management, but if you only need a calendar, some of those features may go unused.

5. Fantastical Calendar

Best for: Apple-device users who want calendar and task tools in one app.

Fantastical handles events and tasks, with several calendar views for checking your schedule. Meeting scheduling is one of its more distinctive features, so it’s worth a look if arranging meetings is a regular part of your calendar use. You’ll get scheduling and task support in the same app, though that may be more than you need for a basic event calendar. Before choosing it, consider whether you’ll use both the meeting tools and task features.

6. Simple Calendar・Schedule app

Best for: iOS users who prefer a simple calendar with essential features.

Simple Calendar aims to keep the calendar experience pared back, with an emphasis on essential features. Its appeal is that it doesn’t try to add a larger set of planning tools. That may work well if you want to manage your schedule without extra layers for tasks or habits. The available description doesn’t list its functions in detail, so check that it covers your needs before making it your main calendar.

How we picked these apps

This list covers a range of calendar needs, from managing everyday events to planning tasks or keeping things simple. It includes two Android apps and four iOS apps, so your device will narrow down the options first. We focused on clearly described features such as calendar views, shared calendars, reminders, and syncing. The right choice depends on which calendar services you use and whether you want a focused event calendar or a broader planner with tasks and other personal planning tools.

Frequently asked questions

Calendar app or planner?

A calendar-focused app is a good fit if you mainly need to create events and check your schedule. Choose a planner if you also want tasks, reminders, notes, checklists, or habit tracking alongside your events.

How do I narrow the options?

Start with your device. Google Calendar and Any.do are the Android choices here; the other four apps are for iOS. Then decide whether you want a simple event calendar, shared calendars, or extra planning tools.

Do views and syncing matter?

Different views make it easier to check a day, week, or month, while shared calendars can help you coordinate with others. Syncing varies by app, so make sure it works with the calendar services you already use. Pick features that suit your routine, rather than automatically choosing the app with the most tools.

The verdict

Google Calendar is the strongest overall pick, thanks to its event organization, multiple calendars, customizable views, widgets, and task support. Any.do is a good runner-up for Android users who want a to-do list alongside their calendar. On iOS, consider Calendar for bringing accounts together or Simple Calendar for a more pared-back experience. The best choice comes down to your device and how you like to plan.
