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.

Customer Reviews

Best calendar app by far!

I am using the free version on an iPad Air with iOS8x. This app runs smoothly and has never crashed on me. It syncs with all my calendars (family and business) without problems. The one minor weakness is the time/date entry. When adding a new appointment and setting the time/date, often either setting can jump to a different setting and then has to be corrected, even jumps to a week rather than just the one day set. Easy enough to correct if noticed otherwise can be annoying if missed, hence one star down for me.(This could be my free version or my system or an app bug). Still the best app out there though.

Satisfied user

This is a really elegantly integrated calendar and tasks (aka "reminders") app. The best bits for me are:
1. The way it works with the native calendar and reminders apps, so you get automatic syncing and backing up; and
2. The way you can rearrange the tasks MANUALLY, with your finger, just like in the native Reminders app. So you're not stuck with some rigid machine-imposed order (alphabetic, etc).

I've tried quite a few apps of this kind and this one gives me the best blend of ease of use, order and in-the-moment flexibility. Five stars!


Awesome calendar app. Just fantastic. It's so easy to use; easy to add things, navigate and search for things. And it looks great too!

Only niggle would be that you can't set a specific time for a reminder/alert of an entry; you have to set it as weeks/days/hours/mins before the event, rather than X time on X date. Would be useful to be able to do that - but not enough of a niggle to knock a star off, in my opinion.
