You can manage multiple calendars, create linked calendars, and receive updates across all devices. Seamless integration with other Apple apps like Apple Maps, FaceTime, Messages, and Mail makes it highly convenient. Apple Calendar is free and offers essential features such as customizable notifications and quick task management. However, it is only available on Apple devices, which is a limitation.

BusyCal is designed to save valuable time for those with busy schedules. It's a popular choice for Mac users due to its versatility and customization options, including the ability to modify ideas, create custom updates, and color-code events.
