Comparing Between Calendars By Readdle Or Google Calendars? Read This


Having been a long time user on Calendar by Readdle, I wanted to compare it with Google Calendar. This is what I found from my comparison between them:

For iPhone/iPad users, go with Calendars by Readdle as it is more optimised for iOS. For users on other platforms, Google Calendar is likely your best bet. That said, both Calendars by Readdle and Google Calendar are almost identical in how they work as a calendar app.

Being quite similar in how they look and function, it can be difficult to compare between them and how their similarities/differences impact you when you use each app.

Calendars By Readdle Or Google Calendar? A User Experience Issue

I spent more than a year using Calendars by Readdle and tested out Google Calendar for over a week and found the user experience on Calendars By Readdle to be better on iOS in 2 significant ways.

First, the copy and paste feature on Calendars By Readdle is super fast. This means that you can easily copy and paste events in less than 2 seconds.

On Google Calendar, you can duplicate events that are created through your Google account calendar but it can easily take up to 5 seconds.

5 and 2 seconds taken to copy an event may seem a small difference, but it would make a significant difference when you are looking at planning the week/month with many events that might need to be duplicated.

Second, the time it takes to modify and move events is significantly faster on Calendars By Readdle then on Google Calendar.

Change is the only constant in our lives and the ability to adapt our plans is essential.

This ability to adapt is mainly exercised through my calendar app and is a major convenience to me. Calendars By Readdle does that well on 2 fronts.

The ability to change the duration and time allocation of an event quickly – sometimes in less than 1 second.

While Google Calendar allows you to change the time allocation of an event quickly, you have to tap significantly longer to change the time allocation, you also have to tap into the event to change its duration.

Because of how easy it is to insert repeated events and adapt my plans on Calendars by Readdle, I’ve found Calendars by Readdle more optimised for iOS.

Before you choose to go with Calendars By Readdle or Google Calendar though, other than my perspective, it’s probably important to have an objective, unbiased look at the similarities between each of them too.

What’s Similar In Calendars By Readdle & Google Calendar

One of the immediately noticeable similarities between Calendars by Readdle and Google Calendar is in how both apps offer a daily, weekly, monthly and list/schedule view. We’ll talk about that in more detail next, but here are 6 similarities at a glance:

  1. The views
  2. Search function
  3. Allows for multiple notifications
  4. Allows copying of events
  5. Ability to sync to different calendar services
  6. Can be used as a reminder app/task manager

1) The Views

Both apps offer a daily, weekly, monthly and list/schedule view.

The daily, weekly and monthly view shows you in detail your plans for each time period.

List/schedule views are identical except in how each app names it – Readdle names it list view while Google names it schedule view.

The list/schedule view shows your plans (or lack of planning) in a scrollable, linear sequence.

Check out how the various views looks like between the two apps through these screenshots on my phone:

2) Search Function

While this function is a common feature among most calendar apps, it’s worth a mention – both apps allow you to search within all your added calendars to find events, tasks, birthdays that you might’ve missed out on.

I’ve found the function particularly useful for looking for birthdays of my loved ones and for events that are scheduled far ahead that I may have forgotten about.

3) Allows For Multiple Notifications

This function for multiple notifications means that you can have 1 event and set up many reminders to pop up on your phone leading up to the event.

Both apps allow up to 5 notifications to be set up per event.

While both apps allow multiple notifications to show for every event that you create within the app, only 1 notification can be set up for tasks on Calendars by Readdle and Reminder/Task for Google Calendar.

4) Allows Copying Of Events

This is one of the key features that I looked out for when I was looking for a calendar app to go with long term.

As most of us will have something resembling a routine that we work on on a day-to-day basis, having the ability to copy events from one day to the next can save a lot of time – this is a feature that both Calendars by Readdle and Google Calendar offers.

Based on what I’ve experienced with both apps, Calendars by Readdle can copy over an event much more efficiently.

Because of how Calendars by Readdle functions as sort of a “host” to the other calendar services (ie. iCloud, AOL, Yahoo) you can copy the events from all these calendar services without issue.

In my experience, the same can’t be said of Google Calendar as it can only duplicate events that are created by Google Calendar itself.

This means that events created by your linked iCloud, AOL, Yahoo calendar cannot be duplicated on Google Calendar.

5) Ability To Sync To Different Calendar Services

Both apps allow you to sync to a variety of calendar services (ie. Google, iCloud, AOL, Yahoo).

As Calendars by Readdle is a 3rd party calendar app, you will need to add a calendar service account before you start using it.

Services that they support include: Google, Exchange, Outlook and iCloud.

By default, a Google account will have default calendars already created for you so you do not need to connect to other calendar services to it before using it.

That said, you can still add calendars from various services into your Google Calendar’s view through url albeit with the limitation mentioned in point 4.

6) Can Be Used As A Reminder App/Task Manager

For times when you want to add a reminder/task that’s separate from your calendars – Calendars by Readdle and Google Calendar can be the solution for you.

As far as functionality goes, tasks and reminders on Google Calendars work in identical manners.

One difference between how they work is that Calendars by Readdle has a Tasks tab that you can go into to look at all outstanding tasks that you may have while Google Calendar does not have this feature.


Knowing the similarities can help you to compare similar features between the two to see which is the one you prefer.

Knowing the differences between the two can help you see what might be some of the features that you want and that might only be available in one of the two apps.

What’s Different In Calendars By Readdle & Google Calendar

While Calendars by Readdle and Google Calendar has many similarities, their differences can make a huge impact when you are looking for the right app for yourself. Here are 7 ways they differ that might make a difference to you:

  1. Google Calendar has a 3-day view that Calendars by Readdle do not have.
  2. Google Calendar can be integrated with more apps than Calendars by Readdle.
  3. You can add many different types of calendars into Calendars by Readdle that you can’t on Google Calendar.
  4. You generally require fewer taps to access things on Calendars by Readdle.
  5. Google Calendar is available on web, android and iOS while Calendars by Readdle is only available on iOS.
  6. Google Calendar is entirely free, Calendars by Readdle has a free and paid version.
  7. You can export your schedule on Calendars by Readdle. You can’t with Google Calendar.

Let’s get right into each of them.

1) Google Calendar has a 3-day view that Calendars by Readdle does not have

We’ve talked about how both apps are almost identical in how they function as a calendar app even in terms of views available.

The 3 day view is something that only Google Calendar offers. Take a look:

Though I’ve found the daily, weekly and monthly views to be sufficient, the 3-day view in Google Calendar is perfect when you want to plan ahead, but not too far ahead.

This difference is probably not a deal-breaker for you, although the next one might be.

2) Google Calendar can be integrated with more apps than Calendars by Readdle

This should come as no surprise seeing as Google Calendar has 1.2 billion active users.

While Calendars by Readdle does offer some app integration with Zoom, Google Meets and GoToMeeting, you will see that Google Calendar has much more to offer in this aspect.

One of the key integration that Google Calendar has is its integration with Gmail/Google Keep.

If Gmail/Google Keep is your primary email application or notes management application then you may want to strongly consider Google Calendar as your primary calendar application.

This integration with Gmail/Google Keep means that you can create events directly from Gmail. You can also link a note in Google Keep to an event.

Besides integration between Gmail/Google Keep, you can also integrate other apps such as to Cisco Webex, SMS Reminders, Wrike and more.

More examples of app integrations possible with Google Calendar

It’s not all pros without cons for Google Calendar though. For all that it can do, it lacks something that Calendars by Readdle can offer.

3) You can add many different types of calendars into Calendars by Readdle that you can’t on Google Calendar

One interesting feature on Calendars by Readdle is that they allow you to add interesting calendars into your view.

For example, you can add a Premier League calendar with your favourite team and all the days where you favourite team is playing on the Premier League will show up in the app.

Google Calendar do allow the adding of the lunar calendar into view. But that’s just 1 interesting calendar.

Just take a look and estimate how many different types of calendars Calendars by Readdle offer:

Probably more than a hundred.

That’s not all that’s going well with Calendars by Readdle because…

4) You generally require fewer taps to access things on Calendars by Readdle

We’ve covered this briefly. But it goes beyond creating the copying/changing of the duration of events and is such a time saver on Calendars by Readdle that I felt it ought to be covered.

For starters, it takes 2 taps to change views in Google Calendar. In comparison, Calendars by Readdle only requires 1 tap to change views.

It also takes less taps to delete an event on Calendars by Readdle than on Google Calendar.

Of course, there are some areas in this aspect where Google Calendar fares better. But in my user experience, this is the exception rather than the rule.

5) Google Calendar is available on web, Android and iOS while Calendars by Readdle is only available on iOS

If you’re using Google Calendar as your calendar app, there’s not much of an issue to get a consistent user experience when you switch between your devices.

This however, can’t be said if you’re using Calendars by Readdle for it is only available on iOS.

To be fair though, in my own experience of using Calendars by Readdle, I can’t recall a time when I felt inconvenienced because of the lack of available platforms with it.

6) Google Calendar is entirely free, Calendars by Readdle has a free and paid version

Most of Google’s suite of apps come free and Google Calendar is no exception.

Calendars by Readdle can be free. But you’d have to pay if you want the premium features like natural language and interesting calendars.

I’d think it was worth my money. You’d have to evaluate to see if it’s worth it’s for you though.

7) You can export your schedule on Calendars by Readdle. You can’t with Google Calendar

This is probably the coolest feature on Calendars by Readdle.

You can plan out your week and quickly export your planned day/week/month into pdf.

Excellent for getting in sync with your spouse/team.

I’ve used it to share my schedule with my girlfriend and it works well to get us on the same page to plan time together.

Of course, you can just share your calendar with your spouse/team. But maybe you’re someone that values privacy and don’t want to share every detail.

In such a case, being able to export part of your schedule into a pdf could be the solution you’ve needed but never knew existed.

Overall Verdict On Google Calendar Vs Calendars By Readdle

Google Calendar as your calendar app is like the trusty car that has all the basic features to get you around town with not many bells and whistles.

Calendars by Readdle as your calendar app is like a mod you could add to your car so that it looks sleeker inside-out, the app has more features and everything.

What to choose comes down to personal preference, but I’d really recommend Calendars by Readdle if you’re using an iPhone/iPad.
