10 best calendar apps

Calendly, May 18, 2020

There are plenty of calendar apps out there, each one with a different aesthetic and feature set. But what are the best ones, and how do you decide which is right for your scheduling needs?

Start by considering what you need the app to do. Do you need a calendar you can share with your household or one that you can integrate with work apps? Do you just want a simple calendar, or are you looking for more comprehensive scheduling and planning features? Once you know what you want, start comparing your wishlist with what’s available.

To get you started, here are 10 of the top calendar apps out there. These productivity apps and calendar software are easy to use, built with the user in mind and enhanced with a variety of convenient features.

1. Google Calendar

Android and iOS: Free

As one of the most popular planner apps on the market, the main appeal of Google Calendar is its ease of use. You log in using your Google account and from there you can start creating calendars right away.

Google also gives you plenty of flexibility to use your calendars in a way that works for you. You might just create one calendar and put all of your events on it, like a kitchen calendar you carry around in your pocket. You can also create multiple calendars, one for each aspect of your life, so you can view them separately or together when necessary.

Calendar sharing

Google Calendar lets you import other people’s calendars and follow public or private shared calendars. If you’re involved in a team or club that has a shared Google Calendar, you can import that calendar into yours and never miss a meeting again. You can also import individual events using ICS or CSV files.

In Google Calendar, sharing works both ways. You can export any of your Google calendars to almost any other calendar or website of your choosing. You have to do it via browser, not on the app, but it’s still quick and easy.

Third-party integrations

Automatic event generation is one of Google Calendar's best features. If you use Gmail, for example, you can set Google Calendar to automatically import events from your inbox (think flight confirmations, concert tickets, etc.).

You can also connect your Google Calendar with most major productivity apps, including scheduling apps like Calendly and to-do list apps like Trello, so you can easily auto-create events for your meetings and due dates.

How to get it

Google Calendar is easy to get. If you have an Android device, you already have Google Calendar pre-installed, and it’s free to download on iOS. The web interface is accessible to anyone with a Google account, which is also simple to create.

Download Google Calendar on the App Store or Google Play store, or access it through your browser.

  2. Microsoft Outlook Calendar

Android and iOS: Free or with subscription

The grandfather of all life planner software, Outlook wrote the book on a lot of the utility we expect in our tools today. For most of its existence, Microsoft Outlook was primarily a work email platform, used mostly because it made internal communications easier. Over the past few years, though, Microsoft has made significant improvements to Outlook’s calendar function, making it a formidable planner app in its own right.

Today’s Outlook calendar is streamlined and professional-looking with plenty of options for viewing your schedule:

  • View by month, week, workweek or day

  • See individual calendars side-by-side or overlaid

  • View schedules for groups or shared resources (conference rooms, etc.)

Outlook also offers one-click event creation. Just click on a time slot and start typing; Outlook will automatically set up the event. Within the event view, you can add more details like reminders and color-coding for easy organization.

Organize work meetings

Unsurprisingly, most of Outlook’s best features still have to do with work. One of the most useful is the meeting request function, which lets you suggest a time and send an invitation to the participants’ inboxes.

Participants can accept or decline your invitation with a single click. They also have the option, if you grant permission, to propose an alternative time if their calendar shows a conflict.

Delegate access

Outlook’s “delegate access" lets someone else create, change or delete appointments and manage meetings on your calendar. This feature alone could make Outlook the calendar app for you if you have an assistant or work in partnership with someone.

How to get it

If you or your company has an Office 365 subscription, you already have an Outlook calendar. If not, you can get it as a free download from iOS or Android. The calendar comes packaged with Outlook email, which is also worth a try.

Download Outlook on Google Play or the App Store.

  3. Informant 5

Android and iOS: Free, subscription or purchase

With Informant 5 (also known as Pocket Informant or just Informant on your favorite app store) you get your choice of a simple calendar app or a fully integrated to-do list manager. The basic calendar app is free, but you need the paid version to access features like a to-do list, notepad and contacts manager.

For iOS

Informant 5 for iOS has a sleek, modern interface, recently re-designed for ease of use. If you have a paid version, you can navigate the app’s many functions with the new SmartBar, a single-button tool that lets you find any calendar view as well as tasks, contacts or notes with one hand.

The recent iOS update also gives you access to a feature called Triggers, formerly known as Templates. With Triggers, you can create a format to use for related events.

For example, if you want choir practice to always have an attachments section for music, or if you want gardening club meetings to always be highlighted in green, all you need to do is create “choir” and “gardening” triggers. Informant 5 will automatically structure those events according to your specifications.

For Android

Like the app’s iOS version, Informant 5 for Android features a recently redesigned interface with sliding navigation. Move with a single swipe from one day, week or month to the next.

Informant 5 for Android also gives you plenty of customization options, including:

  • Choice of theme

  • Multiple calendar views, like week, day, month, agenda and more

  • Customized multi-day view

Already using the Google Calendar app that came with your Android device? Informant 5 can easily sync with it, so you can manage your events in Informant's streamlined interface.

Informant sync

Whether you have iOS or Android, you can subscribe to Informant Sync for $24.99 and connect your Informant app across devices. Apple users can choose a monthly subscription, but Android users must subscribe yearly.

How to get it

The free version of Informant 5 offers basic calendar functionality. The subscription version costs $2.99 a month and adds features like multiple calendars, tasks, contacts and notes. You also have the option to buy Informant for $24.99. When you do that, the advanced functions are yours to keep.

Download Informant 5 on Google Play or the App Store.

4. TimeTree

Android and iOS: Free

TimeTree markets itself as “a calendar made for sharing.” It was built to help users manage multiple calendars and share them with different groups of people. That means you can have one calendar that you manage with your household, another that you coordinate with your basketball league and even a work calendar for your whole department.

Connect and communicate

TimeTree's features are all about collaboration. A few popular functions include:

  • Event chat: Every event in TimeTree comes with a chat room. Send comments, images and ideas for an upcoming conference call or keep records of past meetings.

  • Keep: With this feature, you can start planning an event, then pause preparations and save it for later. Store all of your notes and lists so that when you pick it up again, you have everything you need. No more pressure to schedule prematurely.

  • Feed: See the progress on all of your events at a glance. Find out who’s made progress on what without having to search through multiple calendars.

TimeTree is ideal for busy people from all walks of life, and it’s extremely flexible. It works for professional teams and families alike, and there aren’t many calendars that can do that.

The main downside to TimeTree is that everyone on your shared calendar has to open an account to use it, but making an account is free.

How to get it

Download TimeTree on Google Play or the App Store.

5. Cozi

Android and iOS: Free or $29.99 per year for Cozi Gold

If you’re looking primarily for shared calendars, consider the popular Cozi family organizer. 

Shared calendar

Cozi’s primary feature is the shared family calendar. Everyone gets their own color so you can easily see who each appointment belongs to. You can even set up reminders and emails to go out to the right people.

Non-calendar features

The upside of Cozi is that in addition to a shared calendar, you also get unlimited shared to-do lists. If you give a to-do list item a due date, Cozi will add it to your shared calendar. Add in Cozi’s pre-built planning checklists and you can use Cozi for all of your family scheduling needs.

Cozi Gold

For $29.99 a year, you can remove ads on Cozi and get a number of additional features, including:

  • Month view

  • Weekend view

  • Quick-search of your shared calendar

Jorte lets you subscribe to a variety of event calendars, from top song lists by Amazon to weather forecasts from around the world. Get updates from the US, UK, Japan and beyond.
