Best calendars for Mac OS and iOS

Calendar is one of the most essential apps for scheduling. Any operating system has an app with similar functions. Besides there are many other third party options available, which have a scheduler, task manager and todo lists.

We've selected apps which are the most suitable for scheduling and calendar managing on both desktop (Mac OS) and mobile (iOS) platforms . And they are the following:


BysyCal is a very handy utility for managing calendars on iOS and Mac OS. You can combine it with such services as Google Calendar, iCloud and Exchange. BysyCal is also very useful for tracking tasks on Mac OS and iOS.

Calendar which can be found in the program main window looks quite simple and doesn't differ from the one in Google Calendar or Apple Calendar app (see below). Display by days, weeks and months is available. In addition to this there is a summary: which is a list of events scheduled for a certain period. In the settings you can customize fonts, colors and time format.

BysyCal infopanel is available via a sidebar and as a separate Floating Window. Via Floating Window it's quite convenient to configure events and tasks settings, add tags and set reminders. Extra fields can be disabled via the settings.

You can also use BysyCal as a simple manager of todo lists. Everything you need can be found in todo section. Moreover, this app supports the tasks from Mac OS standard app Reminders.

You can easily manage BysyCal via Menu bar app. Via it you can create tasks, add events and  etc. without opening BysyCal main window.

BysyCal mobile app for iOS has exactly the same functions as its desktop app thus allowing you to:

  • sync cloud-calendars of different platforms and formats;
  • view events by day, week and month;
  • manage todo-tasks lists;
  • create and set reminders for events.

The cost of BysyCal full version is $49.99.

Fantastical supports CalDAV and Microsoft Exchange, so it won't be difficult to combine all local and network accounts working with these protocols.

This app has a number of notable features that (with rare exceptions) are quite unique comparing to other similar programs. We're going to highlight some of them.

Calendars can be combined into sets and after that turned on / off in a single click. Which is very useful for those who have many different calendars for all life occasions. Depending on your location (e.g. home or work), Fantastical switches between them automatically.

You don't have to open the program window in order to manage events and reminders, as it's faster to do it via Mini Window which is available in the menu bar. Calendar sets and upcoming events are also available there.

Separate apps can be downloaded for Mac OS, iPhone, iPad and Apple Watch and it's easy to sync them with each other, so it's very convenient to use them together. The cost of the whole set is 76.47.ThecostofFantasticalregularversionisthesameasofBysyCalwhichis76.47. The cost of Fantastical regular version is the same as of BysyCal which is 49.99.

NotePlan is an interesting solution that combines several productivity tools. First of all it's a calendar and task manager. NotePlan is available for Mac, iPhone and iPad (mobile apps can be found in App Store). NotePlan iOS version includes task scheduler and diary and also allows you to review upcoming events and make notes.

Calendar is one of the app parts. You can add tasks and events to it. Events can be viewed by month (monthly view). Like in other apps third-party calendars services can be also added to this program (NotePlan can read standard Apple Calendar settings which contain all the calendars).

As in any standard calendar there are also tags, checklists, filters and other features for working with calendars and projects. Notes and events can be used for scheduling for a day. Their statuses can be the following: 'done’,  ‘scheduled’ and 'cancelled'.

Simple markdown syntax (see below) can be used for working with notes. (Our review of the best markdown editors). Notes are stored as text files on iCloud Drive.

Apple Calendar

(already included on Mac OS and iOS)

This standard app combines iCloud, Google and Exchange calendars and can be very useful for those who have several accounts. Calendars can be divided into categories and marked with different colors. You can also sort calendars by location: work / home / travel and etc.

For working together with other users you can simply send them an invitation or grant a permission for viewing.

When creating an event, you can specify not only its time, but also give geotags, provide text notes and set a reminder by email or as a pop-up window.

The main advantage of Mac OS standard calendar is that it has only essential features and nothing extra. There is no need in installing the program or paying for additional features that you're unlikely to use. If you only need to plan events and make schedules, this standard calendar will be more than enough for you.

Though there is also a disadvantage: Apple Calendar can be boring for those who are used to alternative calendars that have task management, Mini Window, an overview of upcoming events and other features.
