LANHAM, Md. (CBSDC) — You don’t want to lose your kids or friends in the crowd when you go to the county fair, so consider downloading a free app that will let the whole group know where everyone is.

Glympse lets you share your real-time location with others, and Glympse Group, an improvement that was added last fall, allows every person in a group to see the location of everyone else.

And if you plan on taking many videos, an extra charge will keep you from losing power just when the kids are at their cutest.

Portable backup power is available for as little as $35 with the Mophie juice pack reserve but charging cases sell for $60 to $100. They include the Belkin Power Pack 4000 and the MyCharge Freedom 2000.

Your smartphone can help you negotiate crowded events with GPS, ticketing, video and in many other ways.’s guide “Surviving Music Festivals with Your Smartphone” is an excellent guide to useful products and practices.
