Even though we've flipped the page on a new year, one of the best calendar apps for your mobile device is still worth making a part of your routine for the next 12 months and beyond. With a good calendar app, you can stay on top of upcoming appointments and events, whether they're personal or for work. But you'll find that some apps offer even more.

Depending on the app you download, you'll also find event management and social features or highly customizable and easy-to-read view modes that you won't find on the built-in apps that come with your phone. 

If you're having a hard time keeping track of all the places you have to be today or you just want a different calendar to manage the rest of the year, the best calendar apps for Android and iOS can boost your productivity and make sure you're always where you need to be, when you need to be.

The best calendar apps for Android and iOS

Fantastical (iOS: $4.99/£4.99 per month)

Fantastical is an iOS calendar that delivers a clean presentation of events in daily, weekly, and monthly calendar views, backed up by really easy reminder and event management. Users can create events through a traditional menu-based interface, or simply type or speak a quick audio note that the app automatically parses into an event (which users can further tweak). 

The app now features a unified interface for the iPhone, iPad, Mac and Apple Watch. More importantly, Fantastical offers helpful features for proposing meetings as well as extended support for to-dos from Todoist and Google Tasks. iPhone users will be impressed by dark mode support plus a new full-screen vertical view; as you might imagine, the app now takes advantage of iOS 14's ability to add widgets to the home screen of your iPhone.

Fantastical offers a free 14-day trial before you're prompted to pay $4.99 a month for the calendar app's premium features. An annual subscription allows you to save money over paying month to month.

Readdle's Calendars 5 is a neat iOS app that does a deft job of displaying everything you need to know about your schedule, whether you're on an iPhone or an iPad. It's got all the requisite views, from monthly down to daily, and natural language support means it's easy to enter new events in plain speech. 

The app also has solid task and event management, which syncs easily with the built in iOS calendar app, Reminders, and Google Calendar for easy event importing. We particularly like the timeline view, where events are categorized with icons for a good at-a-glance look.

Google Calendar service has grown to become the backbone of a variety of calendar apps, but the mobile Google Calendar app itself is no slouch, with a clean and bright interface and a variety of views, such as traditional month and week views as well as more focused schedule views. 

The calendar app integrates with Gmail to give you the option of automatically creating events for flight, hotel, and restaurant reservations based on your emails, and also works in to-dos and reminders, as well as habit-forming goals (pulled in from Google's acquisition of Timeful). It's a feature-packed and nicely designed calendar app that works great.

Woven is an impressive-looking smart calendar app currently that operates like a personal scheduling assistant when it comes to your appointments. Available as a free beta as of this writing, the app currently syncs with Gmail and G Suites (with Exchange and other platforms coming soon), and helps you easily set up events and meetings with smart event templates, availability sharing, map-based travel time planning, analytics, and more. iMessage integration on the iPhone lets you text scheduling links and suggest times or have Woven suggest them for you. 

Woven’s scheduling features make it a compelling calendar alternative for the busy professional, and we’re hoping it gets support for more calendars like iCloud and Exchange soon.

If you haven't looked at Outlook lately, Microsoft's email and scheduling app may be worth a second look. Microsoft integrated features from Sunrise Calendar into Outlook, given the latter app's calendar and scheduling features a shot in the arm. 

In addition to its powerful email functions and MS Office app integration, Outlook on mobile has been improving on its scheduling and events functions, with new Calendar App tie-ins for Facebook, Evernote and Wunderlist (though that latter app is getting shut down this May). You also get  event directions from your favorite mapping apps and an "Interesting Calendars" feature that you can subscribe to for things like sports games and TV shows.

A smart calendar and day planner, Timepage works with existing calendar providers like iCloud, Facebook and Google, while providing some nifty calendar views and easy event creation. 

Timepage's base view provides a simple timeline of the day's coming appointments, with a date tab on the side for selecting specific days of the week.
