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.

  • Me borraron mi calendario! 😱😱😱😱

  • Calendars vs. Apple Calendar

    By Rosenfritz
    I’d like something better, especially for visualizing my appointments, than Apple’s own. And this delivers! I’d like to see an easier way to add notes but all in all this is better than what comes with the phone. It uses the same db as the Apple Calendar, so all your existing calendar items show up. It integrates Reminders as well. All in all, I heartily recommend it!
  • Great but could use a couple more features

    By TsApps
    The visual blocks really keep me productive and able to fit the most into my days. Just wish I could color code by by categories and check off items as I complete them. It would also be good if it would alert people I add via text/alarm. Hope to see these feature added.
  • Requested feature

    By RSConley
    I love the app and it has replace the apple calendar app on my main screen on my phone. The only thing that I miss from the stock calendar app is that he icon has the date on it. Could you please add this in the future?
  • Sharing

    By Kingofthemustachemaker
    Sharing capabilities are via export (not intuitive) and as far as I can tell, only allow you to share your events as a pdf and not as a share link someone else can add to their calendar. Syncing is not intuitive, and I highly recommend not creating the events straight from the app because they lose all functionality across the native apps (including losing their chosen color.) This app functions as a simple viewer. How do I get my money back?
  • Amazing!

    By SpiderMan!!!!!!
    Helps me keep my work shifts on track! Super easy to use
  • The best calendar app I’ve tried

    By tagdj
    I live off the google calendar. This app works extremely well! One of their updates took off a feature I enjoyed, I mentioned it to them and they corrected it. Fantastic customer service!
  • Favorite calendar app after trying many over the years

    By Kjlevine
    Finally, an app that does everything I want in a Calendar, and in the easiest and most convenient manner. Time to dump the three calendar apps that I was using to do the same things that this does.
  • Disorganized with time zones

    By Uwantaresponse
    I travel frequently and every time I am home I noticed that events in my calendar doubles, highlighting two days. I have corrected the events on my calendar every time I get back from a trip. Not worth it!
  • Not much different than phone calendar

    By Use self control
    I’m not sure what I paid for. It’s not much different than the calendar that came with my phone for free. In fact, it’s easier to type it in my phone calendar and then view it in this app, but then it’s like I’m having to keep up with two calendars.
  • Bomb

    By lisapiksa
    Keeps me organized love I can color coordinate my days and events because the iPhone calendar was trash
  • Pretty easy to use

    By rnitleo
    This is a pretty good app to use for day to day life activities. But i don’t understand why if you go back two months to look at your last Dr appt,( just an example) everything is gone. Did I miss something?
  • Single Account only

    By TwinkleCarnage
    The app is beautiful and I would love to use it... However, it only allows for a single account and sadly I have four accounts with multiple calendars for each account. Please add functionality to have multiple accounts!
  • Stellar!!”

    By Mr.GoodBrother
    One of the most detailed functionality sound calendars that I’ve ever used or have come across..” PERIOD.
  • Not Reliable At All

    By Nashaikh
    I added all my appointments to this app for the next several weeks, which was time consuming. It was working fine, and then I opened it this morning only to find that all the appointments I had added were no longer there. This was not a syncing issue. I have been searching for a help/customer service contact number and have found nothing. I will now have to go through all my emails and call several offices to determine when my appointments are and log them into a different calendar. I highly suggest not using this App and, if you do, to keep a back-up calendar.
  • Calendar

    By Eeo11
    The best app of all time. Simple as that .
  • Simply the best!

    By Eyat1
    This app is simply the best by far! Easy to use. I like the reminder function/options. Helped me stay on top of my schedules.
  • Ability to see details in every view is fantastic!

    By I Love Solitaire!
    I use an iPhone and have always been frustrated with the calendar feature because you have to open each day to see the detail. Trying to plan a week and a month requires paper :(
  • Weekends

    By Big Tyme 7
    Why are weekends no long RED in day view???
  • Not nearly as useful as it could be

    By ChelssaTE
    Not enough seeable detail - too many events go off the edge of the page - should simply go down to 2nd line. And Not enough color categories - use patterns for additional items.
  • Waste of time

    By c3 reviewz
    Have to upgrade to enter a recurring event... seriously?
  • Could be better

    By Febarretodp
    It could have the current day showing up at the app icon and the reminders could be much better. It’s too low profile.
  • Did not have a good experience

    By is an app
    I tried to buy the PRO feature but it kept saying NO
  • User Friendly

    By MsttD1
    Fast and easy to use.
  • I love it !!!

    By Ghdaaweyiojv46!43
    Keeps me organized.

    By heosnhrodndhowneo
    This helps me recognize the times and days I have planed stuff. This is an amazing app. If you really want the best help you should get the upgrade. It will change your life forever. You wish you would have this in the good old ages. Producer/ maker of this app please replied back to me I would love to hear from you. Thank you so so much.
  • Calendar Review

    By salty quilter
    WORKS GREAT FOR ME !!! I like the option of being able to check back on calandra appointments; leave detailed notes on appointments; ability to use emojis!
  • Great App!

    By ashleetherealtor
    I love using this calendar because it keeps me on track, very easy to manage, love the different colors, and the reminder alerts. It’s super convenient and I don’t miss a beat!
  • Remember

    By srlinda
    I need a reminder that will repeat every 10 minutes until the event time incase I miss hearing it. Thanks
  • Great app!

    By Callaway34
    Huge improvement over the iPhone calendar. Love seeing an entire week of events with color coding and text visible on one page. I tried the free version for a while & then upgraded. Totally worth it. Highly recommend!
  • I paid almost 20 bucks and the app is messing up

    By Rhyoung92
    To be honest, I don’t know how to rate this app. I’ve bought the in-app extras and it cost me almost 20 bucks. When I open the app, it immediately close. I would like someone to contact me about this because I might need a refund.
  • Best Calendar ever!

    By Riveter33
    This calendar app is awesome!! It lets me share schedules with my relatives, is easy to organize and had a nice variety of user friendly viewing options to choose from!
  • Excellent App! Just one question... (see bottom)

    By zeekool
    First I just want to say that this app his single-handedly changed my life. I have it always showing on the face of my Apple Watch, as well as have reminders on my phone and iPad. I have a lot of trouble keeping myself in a routine, and due to that it is very difficult to manage everything I need to do; I often find myself falling short. I use this app to schedule my days a week at a time, with everything from “Shower” to “Eat lunch” to “Meditate” to “Work” to appointments/etc. The User Interface is unparalleled - it is very easy to quickly read and comprehend the various items on my schedule, they are all color-coded and laid out beautifully in whichever view-setting or device I am using. Then there is the actual depth and the functionality of this app, both of which are in abundance. I can do (almost) anything I want in terms of managing my calendars/schedules/items, with a comprehensive “Repeat” algorithm - to just name one example - and an incredible level of integration into my devices’ software. NOW this brings me to my question: Is there any way to create multiple, separate calendars that do not interact with each other, and that I could switch between easily? (So for example view Calendar A only, use it 90% of the time, but then have a separate Calendar B that I can occasionally swap into view for a totally different set of blocks/events.)
  • Constantly deletes my calendar

    By mp1234567891011
    Ridiculous. Fix this ASAP
  • My preference!

    By NY_Fee
    Love this app! So user friendly, easy to use with options.
  • Notifications Don’t Work

    By Slarvey
    They work for new events but not existing events!
  • I was enjoying it until

    By apparentlyeveryusernameustaken
    It decided to wipe off my entire calendar and I lost EVERYTHING!
  • Functional with drawbacks

    By JoLemur
    This is a good functional calendar. I have two complaints. First, all the options for the notification sounds are terrible. There are no deeper sound options and most of he options are high pitch and anxiety producing. Second, the app icon is ugly, and I wish the current date was displayed on the app icon like the default apple calendar does. That would make it easier to check the date. As well, while the upgrade price to full features isn’t bad, the add on price for getting the moon phases on your calendar is a bit exorbitant.
  • Watch face

    By Fire&Music
    Do you have to purchase the pro to get the watch faces? Can anybody answer this?
  • Watch Face

    By CBK00001
    How do I make this my watch face???

    By JunebugDJMom
    I LOVE this app. I can see my schedule of events and list of daily to-dos all in one view. Or you can see the entire list of tasks in one view. The layout and color scheme is pleasing to the eye. It is easy to add items. It is easy to check off completed tasks. It’s just great perfect. Love it.
  • My calendar app of choice

    By Cheeky Girly
    I’ve used this on my iPhone for a couple of yrs. I recall some frustration in the beginning, but that was simply my learning curve. (Switching between date and time, remembering to hit save). Have enjoyed using after I got the hang of it.
  • Hard to Navigate

    By perpetrator73
    I’m not impressed with the layout and ease of setting dates on the calendar
  • It’s not worth the money

    By AGedela
    I used the app for more than 2 weeks now. Purchased a premium to see if it offers anything great, but no. There are many other apps that provide better UI and functionality than the paid version. I wish I could get my money back! I am deleting this app for the worst possible UI experience. $6+ is an utter waste of money.
  • On able to in large the print

    By Dmgel
    The print is minuscule and you were unable to make it larger. It is very inconvenient.0
  • Love this calendar

    By Julie6130
    So easy to manipulate and view as needed! Much better than other calendar that only displays a black dot to indicate activity(s).
  • Issue.

    By retired_jesvs
    I love this app. It has my life on it, but it keeps blacking out to the home page within seconds of me using it.
  • Crashes Immediately

    By Emilyolson1234
    I use to love this calendar app and used it as my main calendar. But now I can’t even use it, it crashes right after I open it. Very frustrating and disappointing.
  • Disappointed

    By anne8sj
    This app crashes when I try to use the microphone to add an event on my iPhone 8. When I reached out to the company they said “Our development team is already aware of this issue and they'll do their best to fix it in future updates. We are sorry for the temporary inconveniences and hope for your understanding.” But one of the main purposes of actually purchasing the app is to get access to the microphone creating an event easily. I’m disappointed they didn’t respond better to this major issue. They should change their advertising.
