A good calendar is a handy addition to your smartphone, helping you stay on top of upcoming appointments and events, whether they're personal or for work. Several calendar apps also offer variety of extra features — from event management and social features to 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 to start the new year with a different calendar, these 25 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.
Fantastical 2 (iOS: $4.99/£4.99)
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 Day Ticker is especially great, allowing users to view and manage their events and reminders. Apple Watch integration pushes your events and appointments right to your wrist for easy reference. An iPad version takes advantage of the expanded screen space with a more detailed Fantastical Dashboard.
Calendars 5 (iOS: $6.99/£6.99/AU$10.99)
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 (Android, iOS: Free)
Google Calendar service has grown to become the backbone of a variety of calendar apps, but the mobile Google Calendar app (Android, iOS) 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 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 (iOS: Free)
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.
24me (iOS: Free)

Map support can show you an event's location and estimated travel time, and BusyCal comes with to-do list functions that are compatible with the iOS Reminders app. About the only thing we can fault is its bland but functional look.
Outlook (Android, iOS: Free)
If you haven't looked at Outlook (Android, iOS) 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, event directions from your favorite mapping apps, and a new "Interesting Calendars" feature that you can subscribe to for things like sports games and TV shows.

The 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.

SaiSuke 2 (iOS: Free)
Japanese calendar app SaiSuke 2 comes with 11 different view modes, complete with landscape and portrait support to take full advantage of iPhone and iPad screens. That's especially helpful on the iPad, thanks to split-screen support.

A downside, though, is that multi-device syncing requires a premium upgrade.

In addition to the calendar features, the app includes a to-do list function and a built-in diary that allows you to take down notes, complete with photos. Still, it is a fairly pricey custom calendar and some users will be put off by the fact that multiple other functions such as a lunar calendar, holiday calendars, and TV schedules are walled off behind in-app purchases.
CloudCal (Android: Free)
CloudCal is a free Android calendar application that has a cool way of showing you just how busy you're scheduled to be on a given day. Using a system called "Magic Circles," CloudCal marks each day on the calendar with a colored arc roughly corresponding to your scheduled appointments and events for the day, showing you at a glance when you're booked, and when you'll be free.

The app comes with a widget, recurring events features, reminders, and week numbers.
Week Calendar (iOS: $1.99/£2.99/AU$6.99 on iPad)
Week Calendar is a bit of a misnomer, as it does more than just weekly calendar viewing. There's agenda, daily, monthly, and even yearly views. A feature-rich application, Week Calendar walks a tightrope between putting the day's events in focus and swamping you with too many details. Batch edit your events, drag and drop them, search through your calendars, set complex recurring events and color-code your events for easy sorting.
