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.

  • 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.
  • Update made it really inconvenient

    By Problemproblem 38473
    Was a great app before this last update - now quick adding an event sets a time by default which requires extra clicks to set as “all day” whereas before the default was to add objects as “all day.”
  • 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.
  • Works great on iPhone. Not on iPad

    By buckrog1
    Used this many years. Love it on the phone but frustrated by inconsistency on iPad
  • Works alongside iPhone standard calendar

    By MicroChipMan
    More options available like schedule 11 hours before, good if you have a doctor appointment the next morning & need to remember to fast 11 hours before appointment, etc.
  • Time zones

    By albenj
    I travel a lot between time zones. I’d like an option to put an absolute time in say 3:00 pm EST while in California and have it remain the same time when I arrive in New York.
  • Perfect Assistant

    By Mr. Biggzz
    Great app!!!
  • Love!

    By Debb123456
    Thank you soooo much for adding the Apple Watch app!!! SOOO much better to see my upcoming week in bold easy to read font on my watch.... rather than the worthless calendar that Apple provides. (I wrote an e-mail requesting this feature just last month! Thank you!!) I’ve been using your app for a few years now and it’s so easy to use!
  • No so great

    By Ferny Vern
    This might be a better app if you pay for it. But the free has one is frustrating to me. All things that have been entered disappear after the month is up. Many times I need to refer back it is gone.
  • Works all year

    By mommabear2623
    But I’m ready for the 2019 calendar and it’s not updated. I’m frustrated filling in work calendars and it’s for 2018 and not 19.
  • Great app

    By Yasmeen 123
    Great app, eliminates me carrying a pocket planner
  • Not worth the trouble

    By Emmys123
    Enjoyed this calendar for about a year and then upgraded so I could easily do reoccurring events - it’s extremely hard to create them though. It has also started deleting all events (except a few all-day events) after that month is complete. Going to delete the app and look for a better one.
  • Calendar review

    By Kelly Newton
    I like it, but it deletes the previous months calendar events which I don’t like. Sometimes I need to look back at a certain date and it’s all gone.

  • The absolute best and most used app!

    By Mike Horton
    This app is amazing, especially it being absolutely no charge. Me and my assistant have ours synced to the same calendar and there is no way I could do on a daily basis what I do without it. Highly highly recommend!
  • Review

    By mischatm
    Wish there were more colors that were not so similar side by side. Ability to copy and paste and write notes. Otherwise really enjoy this calendar and it’s features
  • Love it

    By tallman27
    Great app it keeps me up to date and on time connects easily to all my calendars and I get them all in one place.
  • Terrible

    By Reinkejohn4
    When i enter the info for a date I am trying to set on the calendar, it automatically sets my time and chooses my date for me overriding what I want it set to... For instance... I missed a family gathering because it was originally planned for dec 16th, I entered "family Christmas gathering"for the description, and set the date for dec 16th, when I clicked done for the entry, it automatically set the date to Christmas day and I did not catch this until the 16 today when it was too late. I cannot attend now because of other issues going on. I told them I was coming and now I cant because your stupid app decides when my event take place regardless of what I entered!!! I paid for this app and I am not happy with this. We the paying user should be able to decide dates and times for events we enter, not for you to randomly switch dates and times like this!!! I understand the automation and intent you have with this but is a nuisance and it really messed up my plans.
  • Why can’t you still type in the exact time for an entry

    By ktcarlin
    I do not like how this update version won’t allow you to write the time in. It erases the time. Sometimes I like having the exact time in for things. Can u please add this functionality back in ?
  • event flairs

    By Suzy6491
    Miss them!
  • Love my Calendars!

    By Peacefulwinds
    Great app! After spending a lot of money and time on bad apps I family found my perfect calendar app! I love this! Love love love!
  • Good month view

    By otown911
    This calendar app is amazing. I love seeing the calendar at month and week view and still being able to read my appointments (not just seeing a dot). I like to use the emoji icons to make them even more legible at a glance. It works seamlessly with my iOS calendar and I can add an event to either one and it works. Awesome!
  • I love it

    By one way lady
    Love it love it love it
  • Helps me be more organized

    By MI Adale
    This app is simple, yet everything I need to very, very easily organize my calendar. I have used it for several years and have been satisfied with it from day one. I use the basic app - it’s complete enough to meet all my needs. I highly recommend it!
  • Love it!!

    By ilyAlexHan
    Easy and great!!
  • Try to find me a better calendar

    By josephjjk
    By far, the most user friendly, versatile calendar I’ve ever used. The ease and recognition of the app to add dates, times of events simply by using key words (ie: Friday, tomorrow, etc) is terrific. The customization of alerts allows for true personalization Unmatched by any other calendar I’ve ever used. Everyone should be using this calendar
  • Could use a new look and include a Dark mode as well

    By bluiflip
    Other than that things seem to work fairly well.
  • A good App

    By MarkGyverH
    I have used this app for several years. Functionally it works great. I wish there was a faster way to clear older events. Also be able to change the look more that just the color.
  • Love Calendars

    By Deb Keane
    I love Calendars I rely on it every day. Seriously I make no plans without looking at it first. Thank you
  • Price

    By momasauras
    I do enjoy the app however I think that $7 for an app for a calendar is a little ridiculous. I’m happy to pay for my apps as are most but let’s be honest... it’s a calendar.
  • Calendar app is amazing!

    By KalolaG
    The convenience of having the info transcend generations and live on through what we record is amazing.
  • FINALLY! An app that does exactly what I want it to!

    By sarahlouiseATL
    For YEARS I have used a paper diary to record mine & my family events as I have never found using an electronic calendar very easy. I always found the imputing awkward and the viewing and interaction frustrating, BUT NOT WITH THIS APP! This has finally turned me electronic!! Great app, highly recommend!
  • Just what every busy bee needs!

    By leslietualla
    Ever found yourself carrying a planner in your purse/backpack because you’re juggling a full time job, a side job, school, and a decent social life?! THIS IS WHAT EVERY BUSY BEE NEEDS! Being a nurse with a confusing schedule, planning a decent life outside of work can be crazy. But ever since I’ve downloaded this planner, I can easily see which days I’m off (that are recurring) months and even years ahead! This app also makes juggling a full time job and a side job easier! I wish I found this sooner! So long notebook planners!!
  • It’s ok.

    By BBQ IS Life
    My only complaint was when we “fell back” for winter, my calendar did not adjust and I had to go back through and adjust everything.
  • Imperative

    By Cool school RN
    I call my app my secretary, can’t do without it!
  • Love it!!

    By lwinans88
    It’s a great app. It would be even better if it worked with apple watch
  • Easy peasy

    By Melrose13125
    Awesome calendar that’s easy to use!

    By Ballardg215
    I love this app!!!
  • Appointment recording

    By Desertphill
    Great for recording appointments
  • Best calendar

    By Pencil26
    I’ve used this calendar for years. It’s easy to use. The color coding helps me keep the family’s schedule easy to manage and be alerted if an event is coming up. It’s the best.
  • Great app!

    By Mrslos
    I love this app as it keeps everyone in our family organized and it’s compatible with my Google calendar.
  • Reliable app

    By Bbseagle
    Very handy to keep track of appointments on all my Apple devices.
  • This app makes Organization fast and easy!

    By Desiree '
    I have been using this app for a few years now , I love it , I have a busy life with work and kids, this app makes life a bit easier when it comes to organization. This app is very user-friendly.
  • Best Calendar App

    By Jpa11
    Only complaint I have found is when in the week view it doesn’t default to the current week. It opens at the last viewed week. It seems that it would be more useful to open to the current week.
  • Wish for More Options

    By CynCiCap
    Wish there were more options without having to pay. Would still recommend though, it’s a nice app.
  • Long-time user

    By Stocks 2012
    I love this calendar have used others but this one’s got the best features. It’s a great product
