Fantastical 2 interprets event descriptions that you type in natural language much better than Apple’s Calendar. For example, it understands if you append ‘alert 30 minutes’ – which Calendar doesn’t – and it uses animation well to show it’s recognising things as you type them. You can also tell it to switch to a set of calendars automatically, based on your location.
