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.

  • Great App

    By Mike Chizzo
    Awesome and extremely easy to use. Love that it syncs to my Google cal. I input calendar items at work and then have them available for a quick view when I’m on the go through this app. Love it.
  • Love but having Problems

    By Nanna302
    Wish I could give 5 Stars Love this app have been using for years. All of a sudden within last week when I try to set an appointment it only allows me to set it for the next day. Not a month or 6 months in advance. Please fix this I don’t want to have to delete app because it’s not working right.
  • Amazing Calendar!

    By Hula girl 21
    This calendar is so easy to use and I absolutely love that I can see the whole month with all my plans showing at one time. Unlike the Apple calendar that comes on your phone that only shows a dot if you have something scheduled on a specific day but you won’t know until you click on that day what is really going on. I also really like scheduling plans in different color for work and one color for personal. Helps keep me organized!
  • Love this calendar

    By JaneRN2b
    I’ve used it daily for over a year and it’s perfect! It’s got everything I need in an uncomplicated format.
  • Decent

    By lodelaro
    I docked a few stars because it duplicates everything and syncing between devices doesn’t work.
  • Best calendar

    By Lidebug
    I am a hair stylist and I searched for a calendar that would work for booking my clients easily, and found this one. I Love it! I can see the week I’m currently in, also it’s easy to move to the next week or the next month as my clients like to schedule in advance. I would recommend to anyone ho is a professional or it’s easy to use for personal scheduling also.
  • Love it !

    By she8228
    I use my calendar every day, I have so many bills and it alerts me. Don’t know what I would do without it.
  • Holidays

    By wjifbeicbe
    I wish it gave me the option of choosing which holidays I want included. As is it’s all or nothing.
  • Easy to use

    By haywoo999
    The app works well and is easy to use. It’s simple which I like.
  • Can’t live without it!!!

    By CaroCili
    Love so much the easy way it’s designed. Specially the complete week view!
  • Like this app

    By youngbnh
  • Good

    By Jen B Ku
    Great shared calendar. I wish I could attach pictures in the details. That would be helpful for events.
  • Best calendar app I’ve used

    By Cpas2341
    Can’t stress enough how perfect this app is, been looking for over a year for the best calendar app, finally tried the free version, and two days later bought the paid version, 100% satisfied.
  • My favorite calendar app, bar none

    By DrWeirdMan
    I have tried several calendar apps and this is my favorite. I’ve been using it for a few years. I love the look and feel of Readdle’s app. In particular I like that you can see event details from the month view, unlike the native iOS calendar app. Also, shout out to the developers for great customer service. I submitted a suggestion a few months ago. Not only did they reply right away, but then yesterday they emailed me again to let me know they had implemented my suggestion in an update! Awesome! Keep it up, Readdle! 😁
  • yearly view

    By yeobo808
    like this app, would like it to have a yearly view too
  • Two emails synced up?

    By ikrttt
    Can we merge two gmail accounts on this app ?
  • Ugh

    By Missy G. 21
    Doesn’t sync properly. Duplicates things. It’s just a mess.
  • Frustrating

    By joshskys
    App changes times of certain activities in the day that were already scheduled.

    By Nadine M.H
    Best money I’ve spent on an app. I’m in college with many things going on practically non-stop. I have to show up often to meets or I have personal goals that need consistency to accomplish. Helps me stay on top of my game definitely. Thank you so much for making this.
  • I love it!

    I really like that I am able to add a lot of things on this calendar! I also love that the labels are colored!!! Helps out a lot!
  • Awesome Calendaring App

    By tj-1492
    I love this app. It is been a great resource for me to use. I use it all the time. What I really like is how many reminders you can set and at all the different times. I also love that you can put in addresses or other special notes and that connects directly to your phone and your GPS.
  • Coolest Calendar

    By DarqueMood
    But how about more colors for the items???? What about options for background colors????? These would make it 5-stars for me!!
  • Good program

    By AllBizAllBiz
    It’s a good calendar but they need a notes tab
  • only supports ios and/or android calendars

    By DeliverTheNoise
    if i wanted either of those calendars. i would use them. i want a calendar separate from those applications and entities.
  • Tasks

    By Calx20
    I really like it and all but i hate how my completed tasks disappear from the calendar and so i have to go into inbox to find previous tasks, also occasionally some of my events would disappear and when i make it again they come back. its cumbersome.
  • Price ?

    So we get the nothing special, regular calendar and you want us to pay $14 bucks for more basic features? Riddle me that.

    By Kit i.e.
    I’ve been using this app for three years... Easy to set events and reminders... Love it...
  • So far so good! But...

    By homedawwg
    So far, I absolutely love this calendar. It’s not hard to learn (like other planners on the App Store) and adding on your itinerary is super fast and simple. Amazing UI, and the format of how the weekly view is set is perfect! Not cluttered and doesn’t come with confusing options, unnecessary notes, and gestures. Downloaded it and ended up buying the premium right away because of how easy it was to switch from my old calendar to this new one. The only things I really wish more for this app is: 1. A dark version? Please tell me you guys will make this an option soon! As clean as the current design is, it sometimes strains my eyes just a tad especially if I’m trying to edit my calendar at night. 2. An easier way to switch the daily/weekly (most important for me)/monthly view. Although the current method right now isn’t terribly hard, it’s still annoying to have to press the 3 horizontal line menu and then switch from there. I wish there was a gesture you can easily implement to make this faster especially coming from someone who works 2 jobs and needs to be able to switch from daily to weekly view quickly. (Maybe a swipe down and then being able to swipe left and right to change between views? Just a suggestion.) Other than that, no complaints. There’s so many calendar apps out there with SO much clutter and some with a ridiculous learning curve(ahem I’m looking at you sorted). Trust me, I’ve tried a ton. But this one—so simple and almost everything I would want! By far the best one I’ve tried to date.
  • Help

    By Jacque1113
    How can I add my husband to this calendar so he can see what events are coming up for us on his phone too?
  • Best app ever!!!!

    By WannaBeFree
    Wow - I have REALLY struggled in looking for an exceptional time management app!!!! This delivers!!!! Out of the park!!!! I can do all sorts of stuff with this. Search over. Clear out. Everyone can go home now. :-D
  • Spy application

    By سامي العنزي
    Why this application not working without location????!!
  • Print could be bigger

    By dhd tksndnuhh
    Lots of improvements anyone could think of. Removing the holidays as an option is one. Not knowing what I paid $6.99. Bigger print. Ability to start with any week of the month as time goes by. Pretty good idea.
  • Lost all my holidays

    By CinK130
    Holidays showed up on my calendar for years!!! The start of 2019 and they are all gone!!
  • Calendar

    By tilldale
    Great help with organization!!
  • Horrible User Experience

    By PolarBearKev
    Whoever designed this app needs to be sent back to school. Clunky user interface, lacking specific features like travel time and time to leave. This app is not worth the money.
  • Use this all the time

    By Sasa (say-say)
    I use this app for everything - dates, homework, appointments, events, things I need to remember to do throughout my day, and everything in between. It’s great! :)
  • Does not have multiple alarms.

    I downloaded this because Apple calendar only allowed two alarms for an event. This is even worse, you can only set one alarm and if you have two alarms set in your Apple calendar it will erase both of those when you try to set a third one. Uninstalled due to uselessness and waste of time and space on phone.
  • Works great with other connections

    By ElevatedtoExcellence
    This is a great calendar because it connects with everything like your emails and other devices. I wish it showed the date on the app like other calendars, so I could see the date at a glance without having to open the app. But it is a convenient calendar.
  • Money grab

    By Russ5277
    3 times I have paid and every time I get a receipt from Apple showing I paid. I contact the developer and they just respond with standard answers and don't help and don't refund the extra payments. I'm really disappointed as I just want to use the advanced features. So much promise and so little delivery. Poor form.
  • Love the color option.

    By Feed the muse
    Has everything I need to keep track of both personal and work appointments and tasks. Being able to color code tasks is especially helpful to alert and find groups of tasks.
  • Works and syncs better than Apple calendar

    By abridges01
    I find it works and synchronizes better than the calendar provided with the iPhone and iPad
  • Good, but not perfect

    By PI3141596
    I’m a big fan of Readdle apps, and their customer service is excellent. So when I started looking into iPhone calendar apps, I tested their free Calendars with the intention of purchasing the full version 5 down the line. There is much to like about the free version. It’s an universal app, no separate iPhone and iPad versions to buy. Its day, week and month views are much better than those of the Apple IOS and Fantastical apps. Creating events is generally easier than with Fantastical. Its widget is also quite good. On the downside, I can’t modify or move events that were imported into Calendars from another program. Both the stock Apple calendar and Fantastical can do this with no problem. I also can’t easily go to a specific date (e.g., December 3, 2012), again something the stock iOS calendar and Fantastical can easily do. At this point, the jury is out. I’m going to hold off on buying the full Calendars 5 version until I see if some of these things get fixed.
  • Unhappy

    By costipated
    The app suddenly stopped allowing me to add different colours. I contacted company and they did not reply. I will delete this app when I find a replacement calendar:(
  • Easy!

    By KathiJoH
    It would be nice if there was a search feature in this application like there are with other ones. But other than that it works great and it’s simple and easy.
  • Easy to work with

    By inabaum
    I really love this calendar. Easy to get use to and navigate! I finally found something that is sustainable.
  • Alternative calendar

    By riazi11
    This app needs alternative calendar. specially Persian calendar. Hurry up readdle
  • Notifications/alerts stopped working

    By High G Flyer
    Loved the program until alerts and notification stopped working, and all settings are correct. Can u provide assistance ?
  • Calendar

    By AEG#1
    It’s a good program, but to enter an appointment, you have to do it backwards.
  • Love!! Except 1 Thing

    By honeyylei
    I absolutely love this calendar app. I have never once thought about switching back to the calendar provided on iPhones. There is only one thing that tends to annoy me. Why do all of my events slowly disappear? This is extremely inconvenient when I am trying to go back and remember when a certain event happened. I scroll back to the month and all of the events I had entered are gone, the month is clear. I really need my events to stay on all months.
