4.7 out of 5, based on 61,542 reviews.
What people like
- Works well across different devices.
- Easy to use and clear.
- Great for combining multiple calendars.
What they complain about
- Events sometimes disappear completely.
- Syncing breaks frequently and often.
- Support never actually replies.
- Many features locked behind paywall.
Simple. Helpful.
I just needed everything in one place - one calendar does that and more. Worth a look!
Does not sync
It will not sync with all of my calendars, though it says it does. This has caused me to miss important appointments. Do not waste your time on this calendar.
Just missing widgets
Great app but I can’t find any widgets for my MacBook.
More options needed
Not enough custom options like color coding events. Had to pay before figuring this out.
Have to pay for Premium for each device
This is the first app I’ve used that wants you to pay for each device you want to use the Premium version either Android or Apple. It would be nice to pay once and use on both iPhone and iPad. I haven’t tried adding new events, but it at least got my multiple calendars displayed correctly from the start. I hope there will be an option to change the widget theme soon.
Love It So Far
I like this calendar a lot. Very easy to schedule appointments.
Hard to connect
Cannot connect to iCloud as it stated
Some widget stopped working
I have a paid subscription since I really like this calendar. For some reason, the widgets don’t always work. I have tried to delete it restart my phone reloaded it and synced it but it’s still happening. Other than that, it’s a great app.
Not good enough
They need to come out with more colors, fonts, areas to use emojis, and a todo list area!!!! Then this would be my favorite of all time.
NOT Fair, free for Mac $5.99 for iOS..
This seems like a nice capable calendar app but there is no capability to easily transfer your account access from one platform to another, you have to manually enter access codes, not a show stopper but annoying.. When I started working this on MAC, I liked it. Little did I know that when I wanted to use it on my iPhone it’s free to download but there are some very necessary features that you have to pay for like changing calendar colors (if you have more than one persons calendar displayed).
Easy to use
Great calendar. Very clear. Better than any other calendar I have tried. It is my go to calendar.
Please fix bug on latest update
All my all-day events got disorganised!
Like it
The features I love about this is that we’re able to sync our older calendars, use across our family, etc. etc. Love. What I wish it had was a button for “Today” to take us back quickly (like iCal).
Not worth the bother.
Not very reliable at all. Buggy and you can’t custom colour individual cells. Problems with synchronising constantly. Very dated looking. needs a refresh.
Need to fix latest update
Minor bugs on interactive interface need to be fixed. Invites tab also disappears after some time. Need to quit and re-open to bring it back.
OneCalendar
Hi
Quickly Deleted
I downloaded this do I could add just one of my iPhone Calendars to it. The app insists on importing them all. No thanks!
Basically perfect.
Only problem I have is that I payed for pro and now the widget absolutely WILL NOT reload. I have never had this problem before. Still a great app, I hope they fix the widget.
Very disappointed with it.
Not that different from the stock calendar. It’s not as customisable as suggested. You cant even set individual colours for events. I wouldn’t recommend it.
Used to be better
The App has changed you used to be able to drag and drop the appointments about this was much better and also there used to be a smaller calendar in the top corner.
Phenomenal
I love this calendar! It’s simply formatted, easy to navigate and I have an HP laptop, apple iPad and an iPhone and the calendar is synced online to all of them so it doesn’t matter where I’m at or what I’m doing I can put something in whichever devise I’m on any time of the day. Works great highly recommend 🙏🏼
Error adding your iCloudDevice account: Arg_NullReferenceException
I’ve put in the right credentials and it won’t let me get past this error message… I have tried deleting the app and restoring it to no avail.
Data
More flexibility how interaction is made with Copilot
No auto discovery for cal dav
Looks good but I use a caldav server and cannot seem to get the direct URL to work. Other calendar app’s automatically find all my calendars just by giving my account info and the top level server url. Even allowing direct access to the system calendar would work but that’s not an option either.
Please fix this bug
I tried repeating an event but when i create it for some reason shifts the whole thing one day back??
GREAT APP
only one that really syncs across outlook and gmail seemlessly.
can’t edit
unable to add an event (!) AND unable to “connect” to the simple mac calendar. Sheesh - what’s the point?
I’ve replaced native with this
Good calendar, reliable and syncs well with native. Nice to have detailed view of daily things in monthly view. However, DEV — *** PLEASE 🙏🏼 include ability to insert my own picture from camera roll for the background ***
Very restrictive features
This used to be such great app. But it’s so restrictive now. There’s no longer colour coding, you have to delete and re-enter activities because you can’t edit them if you need to change something. Switching activities from one calendar to another isn’t possible. Basic features taken away because they want you to purchase their premium version 👎🏻
Great for PC - not so great for Mac
I loved it on my PC, but it isn’t as good on Mac, which I now use instead. I’ll stick with it for now with the hope that it’ll improve.
Ease of Use
One Calendar is user friendly. It also looks great when displayed. Overall, I have no complaints at all.
Data Missing
After swiping left or right between months only half or none of the titles are not visible. In order to make them visible you have to click on each one individually. This is the same on both my MacBook Pro and and my Mac Mini. This is a shame because I love the app otherwise.
I like it
I like it, the only thing I wish it had was recurring events
need to fix issue
Would be a great app but it keeps loosing the ability to sync.
Lack of filters
I had the ability to add color coding and emojis to my days. I miss that.
For me and spouse
One of us has iCalendar the other has Google calendar and this allows us to work with each other’s calendars in one place. Works really well so far. Very much appreciated.
Poor support.
I have emailed for support twice in the last month but have not received any reply whatsoever. Now looking for a similar product. Does anybody have any suggestions as to what I could replace it with??
Great Calendar
Just wished it showed current date on the App icon itself like the Apple calendar app does
Requires an Account
Requires creating an account to start putting anything in. They lost me right away with that.
Constantly desyncs
Get so tired of constantly having to sign back in and repair. Almost a daily thing.
Works Seamlessly
I had used it for a long time and tried another calendar for the last 6 months - a big mistake. One Calendar and One Task works seamlessly within the Apple ecosystem. The options, include Themes, choice of personal colors, views etc sets this app apart from the more mundane. Functional is easy and productive. The week calendar view allows viewing the entire week on one page. If you also download the One Task you can add events and tasks from within the One Calendar app. The tasks appear in the calendar day and can be marked completed or amended.
Errors
I am getting notification to add an account before I can add some entries in the calendar. When I go to Settings and try to add an account, it is written account already exists. Waste of time. Uninstalled.
Simple and focused
Very simple, straightforward app. I like its focus.
Not sure...
Was really excited about this app which is why I bought the premium edition.. love the simplicity of it HOWEVER I would like to add more appointments or be able to change the colour of the appointments on the calendar screen however it only gives me two colour options... am I just doing this wrong? Ok giving a 2 star rating for now until developer can either change this or help me. Thanks
Good but has issues
Love the flexibility of this app, drawing in calendars from all platforms and devices. However I need to print monthly calendar and despite trying I cannot get it to print clearly on fonts. Onscreen it shows white text on coloured tabs but when printing it is black on colour and indistinguishable. Contacted their support to find way of changing font colour on tabs three times and no response so very disappointed on that!
Easy and convenient.
The only thing I would add are the dates of the major holidays.
To My Horror…
I was using this app perfectly well until this morning when I found ALL events I’ve ever entered into the OneCalender, have completely vanished. I rely on this calendar as a lifeline for all my chemo, treatments, medications, Dr appointments, etc, and now my calendar is completely bare. Don’t download as not worth the risk!!
Show what date it is
I like the app but I would like to see the date on the app icon without having to go into app.
Synchronization completed with error
I am using the premium for my laptop. After a few weeks I got an error on “synchronization completed with 1 error”. It keeps on popping up and it’s annoying and I could not remove it! Hope you can put an option to easily remove it.
Good calendar, one complaint
I really like this calendar. I have it on my laptop and on my iPhone however, I paid for premium on the desktop version and this doesn’t sync with my iPhone despite everything else syncing over fine. When I try to use premium features on my phone, it says I need to pay. As I use it more on my phone than my laptop this is really disappointing.
