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, SMS 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.

- Get SMS reminders -
Calendars allows you to set SMS reminders for all events, you just need to add your phone info to the Google Calendar settings. It's much better than Push notifications!

- 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.

Good but still but still some bugs

Like the app, but it does have issues. Don't like that I had to buy an upgrade in order to put multiple alerts on an event. That said, now I can put as many as I want which is helpful. The app is often very difficult to change times on an event. If you just want to change the end time it automatically changes the start time. Then when you go to correct the start time it changes the end time again. I often end up deleting and adding an event simply to tweak the start or end time. This is truly frustrating. Also wish I could make the font bigger.
Other than that, I like that it automatically syncs to all my devices and is even updated when I use Apple's calendar. This one is easier to use than Apple's in my opinion. (If they get the bugs out.)

I 💜 this App!!!

I HATE the standard calendar on my phone because I wanted to view the week and could not. So I went looking for a better one and found quite a few. But this calendar is the best of all the ones I found. It offers several different ways to view your calendar, color codes your appointments, synchs with my outlook calendar, even places Facebook events in you calendar if you opt for it! IT'S GREAT!!!
I did pay the $7 for the upgrade after using this app for over a year. I wanted to make sure I really liked it before spending the $. It's totally worth it. Tip: right around the holidays the app went on special for $3. I should've jumped then... Don't make the same mistake I did. 😊

Helpful for isolating a Google Calendar feed

Helpful for isolating a Google Calendar feed for easy monitoring and quick updating.
I'm sure it's great for many other reasons, but I work with a volunteer group that shares a gmail account and the associated calendars and this app is the best I've used at refreshing the calendars (almost in real time) from any changes put out by anyone regardless of their hardware.
It also minds its own business unlike the Google apps I've tried it does not gather and associate other gmail accounts I check or manage for family members or clients into the calendar feed.
It's clean and compartmentalized. Perfect for this particular need.
