With so many people scheduled to hit the road on Memorial Day, a smartphone app is putting the days of trying to gauge when your guests will arrive behind us.
Chicago-based Glympse is a location-sharing app that allows you to alert your friends and family of your location when you're on the open road.
It uses your phone's GPS capability to share your location in real time, including the speed you're traveling and your estimated time of arrival.
You can share your location with another Glympse user, or simply send a url to an individual so they can track you through a web or mobile browser.
A company spokesman says one of the best advantages of the service is eliminating the need for direct communication while on the road -- essentially no temptation to text or call while driving.
The app also offers a group function that could serve you well for purposes other than driving. Think about that next pub crawl or a friend running a road race.
AAA projects more than 36 million Americans will travel during the Memorial Day weekend.
