Calendars by Readdle - sync with Google Calendar, manage events and tasks

By Readdle

Open iTunes to buy and download apps.


Calendars is the most elegant and easy to use calendar application available on the App Store. It works perfectly with Google Calendar and built-in iOS Calendar.

Calendars allows you to manage events both online and offline. Thanks to the unique interface you can move events simply with Drag & Drop, navigate quickly between dates, change event time and reminders rapidly with custom keyboards.

Calendars supports everything you can find in Google Calendar: appointments, reminders and more. Sync is really fast and your information is always up to date.

What makes Calendars great:

◆ Interface focused on events
Elegant and easy to use interface makes it super simple to get a quick overview of the upcoming events and tasks. You always keep your focus on what's important; there is nothing to distract you.

◆ Day, Week, Month and List views of your events.
Calendars illustrates your Day, Week and Month on a small iPhone screen the best possible way. Depending on the situation, select the view that conveniently unveils your schedule.

◆ First-class iPad calendar
It's one of the best apps for the iPad. The iPad large screen is great for managing your daily schedule and enables richer interaction with your calendar.

◆ The fastest Sync
Sync with Google Calendar works really fast and keeps your schedule thoroughly.

What else Calendars lets you do:

- Drag & Drop your events -
You can move and change the duration of your events in a Day, Week or Month view with Drag & Drop. Just tap and hold on the event to activate it.

- Manage your events online and offline -
You can create, edit and delete events at any time. All changes will be synced back to your account once you are online.

- Special Keyboards -
Appointment time and reminders can be defined twice faster than in the built-in iOS calendar, all thanks to custom keyboards.

- Search -
You can search for events by name in the List view. Tapping on the status bar will show you a search field.

Readdle Does It Again

You know how it is. You download and play around with so many apps but, in the end, the ones you keep, and the ones you come to love are those which get the job done simply, reliably and fast. Among those apps still on my iPad after several months of culling are two by Readdle which I rely on daily: Scanner Pro and PDF Expert. I wouldn’t be without them now. So when I found my frustration with Apple’s iOS Calendar beginning to mount, Readdle’s alternative was an obvious place to start. Yes, I looked at others; but, once again, it was the way in which Calendars gets to the heart of what a diary needs to be, syncs perfectly with Google Calendars and doesn’t clutter the place up with semi-useful bells and whistles which has impressed me. It’s intuitive, it’s fast (so far), it’s easy to read if, like mine, your eyes are middle aged and I can’t think of anything I would want it to do that it doesn’t. Once again, well done Readdle. Stable, sensible software at a sensible price.

Perfect for my needs

This is a brilliant app. Very easy to use and very easy on the eye unlike some calendar apps I've used. My only complaint with iPhone is the rubbish calendar it comes with. I previously used Samsungs and loved the calendar function. So easy to use and read. This app gives me that experience on the iPhone. Job done 👍🏻 thanks to this app I now have my perfect phone.


Been using for over a year now and have gone from the trial (free) version to the full (paid) package and is extremely useful for helping me organise my education work, my general employment work, and various day to day tasks I need to remember to do! Recommended to various people highly recommend to those wanting an amazing calendar app that actually works!
