Google Calendar Now Tells You If You Book Your Time Twice on Mobile
Android / iOS: Google is getting better at finding free time in your schedule . It only makes sense that he should be able to tell you when you are going to double-book yourself. It is now possible.
According to a post on the Google+ Gmail feed, Google Calendar will now tell you if there is a conflict with an existing event on a mobile device. When you create an event, the Calendar will show you the possible times you can choose. If there is a conflict, he will mention it below each time slowly. This is a handy way to make sure you’re not doing too many things at once.
