Calendars by Readdle

Calendars by Readdle application logo

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.

Calendars by Readdle Reviews


I am still using it!  GDefenbaugh  5 star

I switched to Calendars a long time ago to manage my Google based calendar. Still using it. Always works. Updated regularly. Good company to deal with. I use other products from them too.


Difficult  JJWTIR  2 star

Difficult to input tasks to a specific date.


Long time user  SketchyAF  2 star

I’ve exclusively used this app for my calendar for over two years now; and it’s been wonderful... mostly. The most annoying issue I’ve encountered, is that when I travel and change time zones, my Entire calendar gets messed up. Ex: it is attempting to tell me that Thanksgiving is going to happen on Thursday AND all day Friday. There is no option to change or edit this. Any help would be greatly appreciated, and then I will give this 5 stars for sure!

Excellent 👍


Awesome!  Bhb9881  5 star

Was so bummed when my previous calendar + was no longer being updated and I couldn’t open it up to get my information from it because it wasn’t compatible with the new update to my phone. This calendar is exactly like the previous one and it actually got all my data from that calendar and pulled it over! With the update I was on able to open my previous calendar and thought I lost all of my information. But thanks to this app I got it all back and I love it!

Sync issues.  Scott Rudzinskas  5 star

Love app on my phone, won’t sync to my iPod???


Limited  Rgems  3 star

Would like to give more stars but I found the calendar limited. Give us at least one day to discover the functionality before you charge us. I don’t even know if I can but attachments in the calendar. So unfortunately I don’t know the limits of the functionality.

Not bad but could be better  attenev  4 star

Good app but could be better when adding a task on a set day. If this could be done my tapping on the day like adding and appointment but you could select task instead.

Great calendar app  AppJoy  5 star

Very easy to manage and visualise events both now and in the future. Coordinates seemlesly with Google Calendar and Apple Calendar.


HP  Hgreek  4 star

Awesome calendar keeping me organised. The only improvement I can suggest is the ability to be able to name each colour so that you don't forget what it represents for you.

Great Calendar App  cuznh  5 star

Love this app, very easy to use and puts my computer and phone calendar all in one place


Love it  nala07  5 star

I've tried several other calendar apps on my iPhone 6+ including the Apple calendar app and this is my favorite of all. It is easy to use and just works. Even I could figure out how to use it without any problems, and that's saying something. I highly recommend this app. I no longer try other calendar apps since I started using this one. I have this app on my iPad Air and my iPhone 6+ and they work together perfectly. Highly recommended.

I like it. I would suggest you to have it on the Apple Watch.


Better than the apple calendar app  nusnna  4 star

LOVE this calendar! There aren’t a lot of calendar apps out there that shows weekly views with meeting details. If there can be a Mac version and also sync reminders to it, it would be five stars!

Michaelle Milly

LOVE IT!  Michaelle Milly  5 star

I’ve been using this app now for almost 3 years I have put my Apple calendar in that folder of apps we don’t use and can’t delete. I prefer to actually see what is on that day rather then seeing a dot on a calendar and this app syncs into all of my other calendars as well which I love. The only thing is I wish there was a log in so when I get another phone all my items are there and I don’t have to re input everything all over again. Because sometimes I do forget to sync certain things.


A little difficult and frustrating  Butchnut  4 star

Features I don’t like are the automatic fill-in. I wish we could manually fill in the states and times something starts and ends rather than having to take out dates dates and times and put others in. Repeating dates are a little hard to fill in, especially once a month , but worse for every other month. My alarms don’t work well. I would like one that is visual that stays until you dismiss it.


Favorite  Maxer0926  5 star

One of my favorite apps

Paid to upgrade for full access to features  Kittie Sayuri  5 star

Requires payment/upgrade to have recurring events, tasks, multiple alarms ... I resisted for a while, but finally gave in. I like it all right. Wish tasks worked like AnyList, but I’m mostly content. 🙂👍🏻
