Apple Calendar vs Google Calendar

Another app category where there’s not much difference between the offerings from Apple and Google. After years and years of development, both these tools have grown into very capable, very solid calendar apps with most of the features you’re going to need, from recurring events to calendar sharing to getting alerts when it’s time to leave for a meeting.
Taking everything into consideration, Google Calendar wins the contest by a narrow margin: it’s one of those apps where the interface really pops and works well (including the default illustrations for events like weddings and birthdays), you get a few more options for scheduling events with others, and overall it’s a bit more intuitive to use. Plus, most of your contacts are likely already using it.
And the winner is… Google Calendar
