A calendar for mac tools is a must to keep track of friends and family occasions, work obligations and deadlines. Without one it’s easy for you to double-book yourself or skip important appointments. Fortunately, there are a number of well-designed apps that make it easy to stay on top of your schedule. The most effective ones are based on Apple’s style and design guidelines, and include native macOS notifications, Today widgets, and menu bar icons, and allow multi-account syncing, color-coding, as well as simple guidelines to help you continue in the right direction.

Fantastical is a user-friendly menu bar calendar that comes with many features. It’s less Apple-like than the other options on this list, but it does all the things that people want from a calendar app. Its left panel for example does not show a list of your calendars which is a waste of space as is the case with most apps. Instead, it has space for an agenda view as well as for reminders. The UI also pays special attention to tiny details. If an event shows up in two calendars, Fantastical displays it with pin-striped patterns that let you know which calendar it’s in.

The free version of Fantastical provides more than enough for most people, but the $6.99/month Flexibits Premium subscription adds an option for scheduling similar to Calendly (which I use to manage interviews across time zones), lots of customization options and unlimited Calendar Sets that can be switched between depending on your current Focus mode, or other factors. It also integrates with Trello and image source Todoist to allow you to transfer tasks from these services into your calendar.
