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.

  • Apple watch

    By MattWarren629
    I would honestly use your app if it had apple watch support. Which would include watch face complications. I know you can do this. Also the calendar integration you have in Spark is garbage.
  • Fantastic app

    Love this calendar app helps me organize my schedule
  • Colors on appointments

    By Kallyn & Nonna
    I don’t know why I can’t make the appointments all one color. Sometimes it will only make a small line. I like the entire appointment colored so I can see it better. Other than it would be a five.
  • Used to love it

    By Lilred4
    Last month I noticed birthdays popping up in my calendar...ones that I could not delete...some were fb friends; some were acquaintances; some names I’d never heard before. Since I could not delete the birthdays, I deleted the calendar app from my iPad.
  • I use this most

    By Lymie61
    I find I use this app most. It isn’t perfect, there are a few things I would change if I could so I have tried other options but I find I still fallback on this. Overall it does everything I need most and I suppose I’m used to it. But in fairness for the most part I like it and it incorporates everything I need. All of that said since the new IOS update it no longer stays open. I have been using it for years now and leave it open on my phone so I can just do the double click and choose it from the selection of open apps or just check the info I need without having to go to it full screen because I leave the month view open. Since the new update however when selecting it from my open apps it reverts to the opening screen and takes a few seconds (seems like a minutes but it isn’t) to open. It opens to my month view again but still each time I go to this app I have to go through the opening wait. This is going to become more problematic for me when for instance I am going back and forth between a couple of open apps while trying to schedule something or while talking to someone on the phone and looking up info. I don’t do this often but when I do I need it to work properly. For instance when I am attending and scheduling doctor visits with my Mom. Update; the app asked for it so here goes (it does not ask for reviews often or obnoxiously) the constant waiting for it to reopen, repopulate is still really frustrating but still using it and I wish it offered either the last thing typed or better yet often used input selection so I didn’t have to type a commonly added item each time.

    My whole life is stored on this calendar!! I love it! 🤠
  • I love this app so much that I fought with my company...

    By JuliaEspinosa let me download it on my work phone. Calendar preferences are uniquely personal; as a busy professional, I demand a lot from my time management software. I need to be able to see the days’ meetings in detail, but also simultaneously in week view. This is something I have long lamented about the woefully subpar iCal app: I have to click on individual days to see the events or sacrifice a more bird’s-eye view. It’s hard to fit both into one phone screen, but Calendars manages splendidly. The trick: vertical week-view lets you see the entire week + each day’s events at once. It’s a UI miracle! I’ve been using this app exclusively for years now, and it has withstood the test is time, as well as the transition from thinking I was busy in law school to actually being busy at a law firm. This app is free so you should try it and see if it meets your needs. Then, buy the pro subscription (for a measly few dollars) for full blown functionality. There are a million calendar apps out there, but none have made me send protracted emails to IT begging them to let me put it on my work phone. That’s how good it is.
