When you are out and have to meet friends, you need to tell them your current location. When you are on your way home, your family needs to know exactly where you are and how you are moving towards home.
Glympse is a simple app that helps you do all that. Just enter the person’s name from your address book and send them your location from Glympse. And you can specify for how long they can track your location. The recipient(s) need not have installed Glympse – they just get a web-link which will show them your current location, for the time period specified. If you are going for a meeting and the attendees are in your calendar, Glympse can send the  message to all the attendees, automatically.
In short, Glympse is a fast, free, and simple way to share your location safely using GPS tracking in real time with friends and family! No sign up required! And, of course, it is free !!
